I own 1999 Mercury Grand Marquis while traveling down the highway our Climate Control Unit totally quit working, you can get anything, at about the same time I noticed that I did not have and turn signals. We have checked all of the different fuses, all tested good. My Wife told me that the front the the climate control unit on the dash seemed to be warmer then the rest of ... Read More
I had the same problem and no one could figure out what the problem was. The local Ford dealership wanted to charge me $70 to hook it up to check the computer but said it was probably the fuel pump or fuel pump sensor. My Mercury is a 1999 model with 74,000 miles on it. It is a one owner car and has received excellent service. My parents gave it to ... Read More
Don't take my solemn word this is accurate, but my research indicates... Error Code 1255 - Fuel Shutoff Solenoid Supply Circuit Failure. Hopefully someone with more knowledge than I can offer you more information.
my check engine lights keeps coming on and the car begins to hesitate when giving gas. Jiffy Lube says it is error code 1255 but doesnt know what that is. Anybody out there know what this code is about?

I wanna say like 5000+ miles maybe... I purchased the car this past May. I changed the plugs, fuel filter and gave it a oil change. I was thinking it was the plugs but in the past when a plug was fouled it would throw a code that theres a misfire. I haven't started it in a couple days due to someone saying it could be the harmonic balancer and it ... Read More
How many miles on your fuel filter?
It could be that the fuel injectors need to be cleaned or some water in the gas but you really need to have a garage look at it to at lease pin point the problem. You will end up running around it circles if you go by "he said she said" try this or try that. Some fuel injector cleaner in the gas is a cheap way to start. Don't put ... Read More

I am surprised to hear of the stiff ride in the 1999 Grand Marquis. I recently purchased a low-miles 2003 GM and discovered after purchase the same stiff ride--almost uncomfortable--for a supposedly luxury car. Doing research I found that Ford stiffened the suspension with the 2003 model. Taking it in to a Mercury dealer for service, I asked the service manager if there was anything I could do to ease this. ... Read More
I have a similar problem on my 2003 Crown Vic and 2004 Mercury Monterey minivan. I feel reasonably certain it is the Goodyear tires I have on them. On both vehicles, the tires need rebalancing after about 3000 miles. Always, the balancing weight position has shifted. The LM dealer eventually decided that one of the tires on the Monterey was bad and after replacement, found a very noticeable improvement but at ... Read More
I am planning to buy a 1998/1999 Mercury Grand Marquis. Currently, I have a 1992 toyota camry with over 200k miles and with no breakdowns since I purchased the car, except for routine maintanence. Can I get some opinions about the reliability of 1998/1999 Mercury Grand Marquis? I travel heavily and the last thing I want is a car that might stop in the middle of nowhere. Thanks.
