The latest incident was on thanksgiving night while driving to a sale at target. thank god I was going slowly because after i let my son out to wait in line, the brake pedal went all the way to the floor. There was a small child about to walk across the crosswalk when my daughter pulled the emergency brake and ... Read More

I have a 1999 jeep grand cherokee with the in line 6 cylinder. The vehicle is intermittently running rough at idle and under load. Under load it will feel sluggish with intermittent surges of power. At idle I notice a little black smoke from the tail pipe and a different smell. The check engine light has come on a couple of times with the P0171 code. The oxygen sensors were recently ...

I had a problem with Air Bag light, CC, horn and radio controls on my 1999 Jeep Grand Cherokee. Each one went out one at a time. I replaced the clockspring which transfers all controls from the steering wheel to the rest of the car. Now all of the controls work and the airbag light is off. The CC light now comes on but the cruise control still does not work. ... Read More
My Cherokee is having so many different problems and I don't know how to handle all of them. If anyone has any suggestions or have had the same problems, PLEASE HELP ME !! The brake light doesn't work on the driver's side only when the headlights are on. I replaced all of the sockets per a mechanic and all was well. Now it is doing it again. I checked the socket ...

Mine has just gone the same, I have a 2000W Cherokee Orvis, my cruise contol has stopped working plus the airbag warning light is on all the time PLUS Ive no horn. I wonder if theyre all linked.....seems a strange coincidence if theyre not linked. If you have any ideas please let me know.
My cruise control no longer works. The light will not come on in the dash. I looked behind the airbag and there doesn't appear to be power to the "on-off" switch? I can not find a fuse? My airbag light is also on in the dash. Not sure if they are related?
I have a 1999 jeep cherokee and in the past few months my jeep has been acting up right after i start it up a few minutes later my jeep starts sputtering and feels like it is going to die and when i stop at a stop sign or stop light the rpms drop and i have to give it some gas so it wont die, but today i was driving ...

I had the same problem on my 1999 4wd GC.You are hearing noise from the front hub bearings. Mine started getting noisy at 135,000 miles. The recommended method to check them (jacking up and pulling sideways on the wheel to check for play) did not indicate they were bad. But, I suspected them anyway because whenever I would spin a front wheel by hand, I could hear the noise (same pitch, ... Read More
I have a 1999 Jeep Grand Cherokee Laredo and the heater just dosent produce any heat. The temperature of the motor is good but the heater just gets slightly warm. I am looking at replacing the heater core but need to know if that is going to fix the problem or if there are other problems I need to check first because the heater core is an expensive repair job.

grand cherokee stalls or dies out. 1) CHECK YOUR CONNECTIONS AT THE ECU (ENGINE CONTROL UNIT) MAYBE CALLED THE PCU (POWERTRAIN CONTROL UNIT) ON THE PASSENGER SIDE FIREWALL. ON 1998 AND EARLIER THE 3 PLUGS SOMETIMES GET A BAD CONNECTION. IT IS USUALLY THE ONE CLOSEST TO THE FENDER. UNPLUG, SPRAY WITH CLEANER AND REPLUG. YOU MAY EVEN HAVE TO WRAP A ZIP TIE AROUND THE UNIT TO KEEP THE PLUG ... Read More
Hi, please could someone help me bear some light on a problem with my Jeep Cherokee Orvis it is 1999 model, and everytime it goes on ice the brakes dont work properly and makes this horrible grinding sound. Otherwise it is perfect, it is definately something to do with the ABS, as when I take the fuse out its fine.
rwengr: Thank you for your reply. As soon as I get some free time, I will try your suggestions and post my result.
If it only happens when you are moving, a connector or wire is loose or speaker or radio not secure which stresses wires and connectors. Next, I assume it happens all the time so you can test it in your garage. Obtain a portable radio or compact stereo that can driive your speakers. The ohm ratings should match or be as close as possible. The Power output of stereo should meet ... Read More
Sure wish you had received some responses. I have a 2000 JGC Laredo with what may be the exact same problem. I have spent a couple hours searching on the Internet, and cannot find this particular problem addressed anywhere. At least I won't assume it's the speaker, after your outcome.
Wife's car. Mentioned it was running better than usual the other day (for reasons unknown); then, said she heard a very loud noise from under the center of the car....not a bang (like a backfire), but more of a 'hit hard with a hammer' sound. Car immediately goes to somewhat sluggish running with 'check engine' light now on. Now, it shifts hard...slips a bit...when auto tranny is shifting from first to ... Read More

I had exactly the same problem and the oddest thing about it was that only the driver's side rotor locked, the passenger side was fine. I got to know the folks down at Auto Zone pretty well too. Did you ever find a solution? I'm driving around right now with one new and one old rotor. Let me know if you were able to find a rotor that fit. Thanks! Altitude ... Read More
Just purchased and ran fine for the first week. Now it skips between 0 - 40 mph. Tried "good" gas, dry gas. Had it checked and they said nothing wrong with transmission and is all they could suggest is a tune up?????
I currently have 2 of these. One does this same thing. It only happens occasionally and is most noticeable at night (obviously). The lights will come on, turn on the motion sensors on the porch, then go off. It is like it is possessed! It has helped to turn off the Auto Headlight function, but that is a pain.
Has anyone experienced these problems and if so, are they related and what is the solution? (My best guess is that it is related to the Automatic Headlight On feature.) (1) When the vehicle is parked with no key in the ignition, the headlights come on, stay on for less than a minute, then go out. (2) When driving the vehicle during the day (with the auto headlamp control in the ... Read More
My 1999 Jeep Grand Cherokee does nothing. The engine doesn't even turn over. The odometer comes up with the word "done". The last time the engine started, it ran for about 2-3 mins, made a muffled thud noise and just stopped. It hasn't started since. Does anyone have a clue as to what is going on? Did my engine blow up or something? What does "done" mean? I'm at a loss. ... Read More
I just purchase a 1999 Jeep Cherokee, 6 cil and 2 WD. The transmission only moves the vehicle when rev up at high RPMs. Can anyone provide input as to the possible causes of this problem before I pay someone to rebuild the transmission? Also, I look under the transmission and the drain plug has a “DII” written on it. Does this mean the transmission uses Dextron II ATF? I read ... Read More
My 99 has 94 factory parts on it. Found out the hard way like u.
I have a 1999 Jeep Cherokee Sport. Bought new rotors, and after putting them on the front wheels wouldn't turn. I checked the sizes and the "stock" rotors are 1/2" (roughly) smaller in diameter. Auto Zone and a belvy of other places cannot help me. Maybe someone here has a part number or knows what they should be? The "stock" rotors given as replacements were 3115's (305mm), the old rotors appear ... Read More
My 1999 JGC is running codes that tell me 3 of my cylinders have circuit malfunctions. I'm not exactly sure what that means but I need some tips on how to repair it.

I have a 1999 Jeep Grand Cherokee, and WAS part of the death wobble club. I found these online forums to be very helpful in solving my problem. The Following was the solution to my problem. 1: new rotors: warped rotors caused an initial wobble that caused steering components to loosen over time. 2. Drag Link: I replaced the draglink tie-rod ends which SOLVED the PROBLEM!!! The initial wobble from my ... Read More
I had a miss at 60mph and up with my 1999 grand cherokee as well. Not 02 sensor that fixed it. Took it to Jeep Dealer and they did not know, finally a transmission shop figured it out. It was bad tires causing the transfer case to shift in and out of four wheel drive. Replaced tires and the problem went away.
how many miles on your jeep? if it were me i would change the oxy sencers on the exaust and see if that helps as they ware out and if still in pramaters of computer will add gas as if running lean when your not thus over fueling engine under load prob have two one in front of cat converter and one behind change them both
My jeep is a 97. The fuses should be listed inside your owner's manual and there should be a fuse for this function. I believe the fuse is for all power window/door lock modules. You will have to double check. Assuming I am right, blown fuse cannot be reason because passenger door works. There is a microprocessor based control module inside your driver door. My recollection is that it cannot be ... Read More

Chrysler has announced they are putting this awful SUV out of its misery after the 2009 model year. My 1999 was the worst vehicle ever owned. No quality control. Over 30 significant problems over a seven year period. Garbage!
First, I assume you mean evaporator. The evaporator is under the dash. I have a 97. I bought the Chrysler shop manual on ebay. In the A/C section they don't give any part info. They do show that heater/air conditoning is contained in an integrated housing. It looks like you pull that out and then hope you can extract the evaporator. Once you have that, hopefully it will have a stamped ... Read More
The AC condenser is mounted in front of the vehicle radiator. If it is bad --replacement is the only alternative. The condenser will appear as a minature radiator. Its job is to release the heat from the cooling process system (as in radiator fin) via the small fins attached to the condenser ( page24-7---- 99 cherokee service Manual) Now if the problem is the evaporator coil( finned device thru which cold ...

Is there a site or link that shows which condenser is for which model and as importantly, how to replace the condenser. I have heard the better part of the dash needs to be removed. Any help is appreciated.
I recently changed my spark plugs on my 1999 Jeep Grand Cherokee 4x4, 4.7v8. I have started to get a miss at high speeds. Gas mileage has gotten poor. Local mechanic says transfer case. I think bad coil plug. No codes shown when tested twice though. Any ideas?
i have a 1999 jeep cherokee sport with an HO inline 6. ive researched and looked everywhere on the vehicle and cant figure out what kind of transmission is in it. Its four wheel drive automatic. thats all i know about it. some help would be great.
I just bought a new 2008 Jeep Grand Cherokee Overland 4x2 and love the vehicle but cannot drive it because the seat has given me lower back pains.

The 4.0 uses the same transmission as the 4.7 up until 2001 (Jeep switched to the 545 RFE for the 4.7 in 2001). The 45 RFE (Rear wheel drive, Fully Electronic) which is used in the 4.0 uses the same electronics as the 545 RFE, but the 545 RFE is for heavier duty use. Jeep also flashed the computers for all Grand Cherokees made between 1999-2000 (keep in mind that they ... Read More
These components do do not bad like this.I have had 4 Jeeps and none of these problems...they are taking DC for a ride. Go to another dealership.
My 2004 Grand Cherokee had the same problem with pulsating brakes as my 1999. The dealer covered all expenses on my 2004 until 40,000 miles, but after that I was told that the factory 12,000 mile warranty would apply. Since the rotors warp between 12,000 and 18,000 miles just like clockwork, replacing them with factory rotors and shoes was not considered to be a good investment. My Jeep dealer mentioned that ...

Please help! : For anyone with a 1999 to 2004 GC that has grinding brakes and has spent a fortune on garage repairs to no avail, I hope that you can all help to find the answer to this question. After hours on the internet I have found out that there was a class action against Daimler Chrysler alleging that the front brake components including the rotors and calipers are faulty ... Read More
Please purchase vented rotors because they cool down faster than regular rotors Jeep's are heavier than passenger and all that extra vehicle body weight causes more friction when the brakes are applied and please make sure you use ceramic brake pads and this will be the end of your break problem issues I promise
Hey, I have a 1999 Jeep Grand Cherokee Limited. I have been noticing a loud creaking noise in the front end I believe it is suspension related.

If you have experienced this or think you may know what it is please let ... Read More

It not the thermostat, or pump, Its the coolent level sensor in the overflow/resovor, should read 3300k ohms, the plug that goes into the back of the screen, under the radio,controls, has a picture of the viechal, tells when a door is open ect... the #1 terminal goes to the coolent level sensor, try cleaning the connector, that usually fixes it, if not sheck the wires.

I own a 2001 Jeep Grand Cherokee and I too, have the same issues with the heater. It will only produce an ambient air temperature from both driver and passengers sides.

The doors are turned by a motor attached to the bottom of the door ... Read More
I have a 1999 jeep grand cherokee that has a popping noise in the front end when turning. I have replaced all tie-rod ends, both bearing hubs, both axle joints, both break drums, replaced all ball joints, and replaced the steering box. And have not found the problem yet, anyone have any ideas???
I Have a 1988 jeep cherokee and a 1999 cherokee and have had the problem with both vehicles. It was a little different for both but very similar. I drove the 88 until the track bar broke. Once it broke the problem was solved. The 99 was much more involved. I bought the jeep from a friend who brought it to the dealership and they told her the wobble was from ... Read More
Thanks for the advice!
Brake rotors and power window operators were two of the weak spots. To fix the power windows usually requires the entire assembly to be replaced and it is common for all of them to be replaced over a shorter than usual period of time. The brake rotor problem is fixed by putting some thing other than factory rotors on the vehicle. I would see if the owner can give you a ... Read More

when driving my jeep at 80km or more when i touch the accelarater there is a pooping sound coming from the engine compartment.
Howdy kser I own an '03 GC Warped rotors replaced under warranty at 10k Warped rotors replaced under warranty at 22k Warped rotor replaced by me at 38k Piece of shit. I guess if you want to drive a jeep, plan on replacing rotors every year. By ther way, the pads last forever. I don't think its my driving style. Also, I've never had the vehicle off road. C

Hi, Does anyone know where the horn relay is on a 1999 Jeep Cherokee? I have to get it inspected and my horn no longer works ever since my Jeep and I went for a "swim". Thanks for any help you can give me! Dina :)
Hi I have a 1999 jeep grand cherokee. I am having the same problem. Does any one know if this method of replacing the relay would work on the 99 model. thanks Joy
My 2004 GC just had it's 3rd set of replacement front rotors put on it in less than 4 years. Each set seems to last 1 year. The latest ones lasted only 6,000 miles. Jeep knows they had a bad brake system in 2003 and earlier. My jeep was manufactured prior to June, 2003.
I have all wheel drive in my Cherokee, it stopped working this winter, I am afraid of damaging it further by driving it as is. Also I have reduced traction with only one drive wheel. The jeep is so powerful i am at a disadvantage in inclement weather due to the reduced traction. Any ideas as to what to do?
Hello all, I bought a 1999 Cherokee Sport. All in all, I really love it. But the driver's seat is in pretty bad shape. Passenger's seat is so-so. I do a lot of long distance driving - 8 to 13 hours at a stretch. Can someone please recommend some comfortable, not-too expensive replacement seats for this Jeep? A website or URL would be nice. Thank you, John Pittsburgh, PA
I have a 1995 6 cyc w 145k miles and had wide swings in oil pressure when driving and at idle. Pressure sensor internal membrane had tear and needed replacement, now working fine. Oil pressure test at 3k rpm's was fine but at idle was lower then factory spec, meaning some internal oil passage blockage. My mechanic recommended running some oil cleaner/flush thru engine before next oil change to dislodge internal ... Read More
Jeep Grand Cherokee Self Diagnostic code #56 says: Right temperature door travel too large. What does this mean, how is it fixed?
Ok, this is dsmans again. First I want to thank all that have commented on this particular problem. On 2/18 I wrote I had experienced the sensor problem. Since then, I have bought it to the dealer. They had the car all day and I called at 4:30 that aftrnoon only to find out that the sensor was checking out fine and that I had no pressure. What they then told ... Read More
I have a 2000 Jeep GC and have just experienced the same problem. Today was the first time it dropped to zero however, and the check guages indicator came on. I was told before from Valvoline that a wire was off and they put it on, but the sending unit will have to replaced eventually if the problem persists. I will have to have the dealer confirm this week.
The climate control on the passender side of my 1999 jeep grand cherokee is not working...only blowing cold air. Any ideas?
when i start my Jeep the oil pressure is a little lower than normal, as it warms the pressure drops, eventually to zero and the check guages light comes on. When I accelerate the check guages light shuts off and the pressure rises slightly, only a little bit! I have plenty of oil, and I had it changed 3000 miles ago. What is my Jeeps problem?
is 6,000 dollars too much for a 1999 jeep grand cherokee limited with 130,000 miles on it.
Hey GrizzlyMidge, I have a 1999 Jeep Grand Cherokee Laredo & just recently have started to have the same exact problem as yours & 99jeep. The driver's side tire makes a persistent "whining" noise whenever I hit 20+ mph, so it is quite an annoying thing to deal with when driving through town. I had just brought it in to the dealer I bought it from, and he thought it was ... Read More
I have boughten an 1999 jeep grand cherokee and it has run great until the other day it just suddenly died on me and ever since then it has been starting fine and then within 20 seconds it dies i thought it was a bad gasoline problem so i bought stp and it ran fine for like 15 minutes then did the same thing any suggestions? please help!!!
My neighbor just went through this last summer on her '00 Limited. I thought her mechanics were trying to take her for a ride, but it turns out the pinion and carrier bearings were shot. While they had it apart, they changed the axle bearings as well. It fixed her problem. Seems like her bill was right at $600 as well. Good luck.
Here is the problem my 1999 grand cherokee 4x4 started to developed a humming noise from the front left side and this sound started at 60 KM/H and really gets louder at 100 KM/H or about 65 mph, as time went by it has become almost unbearable. I took it to my mechanic and he said that it was the rear bearings in the back axle, I did not agree as ... Read More
One other thing. I don't know where the temperature sensor for the fan is located, but if it is in the radiator area the radiator itself would not get hot if the thermostat was not opening even if the engine was overheating. You can always remove the thermostat just to verify you are getting good coolant circulation.
Since you said the fan works if you jump a hot wire to it, the manual mentions only two other things. Check the 40 amp fuse in the power distribution center (engine compartment) and the ones in the interior fuse panel. There is also a relay located at the right front of the Jeep directly under the head lamp assembly. If all these check out, you are into "black box" territory ... Read More
no, the jeep is not hot, but it gets hot very quickly and the fan does not come on.
Is the Jeep hot when you are starting it? The electric fan is thermostatically controlled and only turns on when the coolant temperature requires it.
i have a 1999 JGC laredo with 110,000 miles, V6, 2WD - the radiator fan does not come on when i start the jeep - i can run a hot wire direct and it kicks right off - any suggestions?
I bought a 1999 gand cherokee jeep three weeks ago and it did the smae thing for a while. Also the instrument panel was driving crazy when I was opening the door. Twice the dealer did not find what was wrong but it started running down my battery and just today it cannot even been jumped so I had a truck take it to the dealers again. Now they have to ...

You started the Jeep, heard a "pop", the check engine light came on and now it's running rough??? You probably have a blown head gasket.
My Dad has a 94 Grand Cherokee Ltd. 318CI or 5.2L. He bought it brand new, has 51,000 miles. He has drove Jeeps since 1946, owned since 1948. I get a GM discount of $8,000. to $12,000. off sticker, he still drives & owns only JEEPS!! Today he went to the store, turned the ignition key off, and the blower motor kept running like on slow speed. He took the key ... Read More
I could not agree with you more! And not only that! The dealers knows and they do not fix tha problems either! They are getting paid anywya for looking! My 1999 Grand Cherokee still runs down the battery and no dealer knows why! Hope the electriacina I took it today knows something! It is amazing though that the 2006 models still are having problems... I will not buy another Cherokee ever..maybe ... Read More
I seem to have the same problem with a 97 Model Lossing coolant, funny smell, running rough, how much is a heater core? Regards Desmond
Thanks for your email. I will definetly keep that in mind, because coincidently just this morning, I went to start the car and also turned on the heater (low) and it made a popping sound and then the check engine light came on and stayed on. I was able to drive it but it drove rough and jumpy. I will have to check it out later today. If you have any ... Read More
I had a similar problem on my 2002 GC Limited. A slow but continual loss of coolant. It wasn't a water pump problem. I have the split system for heating and cooling. Drivers side would warm up okay but the passenger stayed cold. A test revealed that the passenger heater core had a slow leak. I never smelled fluid nor did the carpet get wet. Core replacement fixed the problem. Just ... Read More
"Both times I was told the water pump needed to be replaced when the "low coolant" light came on." I've never heard this. However, when a water pump goes out, many times it will start leaking coolant and will cause the light to come on. Just because the light comes on, doesn't mean the pump is bad. You could have a leak elsewhere. Have your mechanic pressure test the cooling system. ... Read More
I have a 99 Jeep Grand Cherokee Laredo which I inherited from my son. My son replaced the water pump once before giving it to me. I have had to replacae the water pump twice. Both times I was told the water pump needed to be replaced when the "low coolant" light came on. Now the low coolant light is coming on again. It seems like every two years we have ... Read More
What are the reasons you have been given for overheating? If the auxillary fan doesn't come on without the A/C then find out why. If it does overheats with the aux.fan on then I'd suspect the radiator internals are partly plugged or have corrosion that impedes heat transfer. It could be a water pump that doesn't pump enough coolant but I'd bet on plugged radiator.
I have a 1999 Jeep Cherokee Sport and the ac fan rarely comes on so in the heat the Jeep will overheat. I can not use the AC or it will cause the car to overheat but if I leave the ac off I have no problems. I have been given every reason why this could happen from many different mechanics. Could this be the thermostat or the blower itself. Someone ... Read More
