• 1999 GMC Safari heat blows luke warm or cool

  Written by: geraldl on Feb 17, 2011 2:14:04 PM

  Heat from vents blows luke warm or cool air. When van idles or I come to a stop, air blows cool. When I accelerate, air becomes luke warm but not hot. When there is stress on the engine going uphill, air sometimes stops blowing from vents, but when I remove my foot from the accelerator, the air comes back, but still luke warm or cool air. Replaced radiator, new radiator cap, ... Read More

  . Early 95 model and older of Astro/Safari vans had single fiberglass leaf system. Mid 1995 and newer years (like my 2001 van), their factory build was 3 leaf steel spring system. For early 1995 and older leaf spring conversion kits, surf: http://www.stengelbros.com/SteelReplacementSprings.htm For 1999 AWD, one can install +1 leaf (mid length leaf) in the rear. This firms up the rear's suspension but it also lifts the van's rear 1.5". ... Read More

• Intake Manifold Gasket

  Written by: wolverine2 on Jan 12, 2010 1:45:29 PM

  Have a 1999 GMC Safari and it was leaking anti-freeze. Mechanic said it was the intake manifold gasket. He said it would be 800.00, While replacing the gasket he says when he removed the intake manifold something must have fallen into the engine and was causing it to knock. He then had to take it apart again and take the Head off to remove the debris and of course charge more. ... Read More

  Thanks for your concern.... For your records, there's a known problem with the ABS system on the Astro/Safari vans. There's an official TSB but NO recall. Still amazes me why no formal recall. For details.... Bottom line is... Defector sensor (which needs to be replaced) or the existing sensor is too "rusted up" to work properly... ----------------- .... Basically, dirty sensor mounting surfaces cause the signal to drop out at low ... Read More

  Have the exact same problem with my 1999 Astro. Fan runs on high only and runs on high even with key out. What was the outcome of your same problem and how much did the blower motor resistor cost you? Thanks for your help

  Our 1999 GMC Safari that has 125,000 developed a ticking/knocking noise on the right side of the engine. I have had some people tell me that it sounds light a collapsed lifter. The runs fine except for this noise. I put in some mystery oil from and the noise is not as nocticable now but I can still hear it. Now when ever I changed the oil, if I do not ... Read More

• 1999 GMC safari blower motor resistor

  Written by: kortic on Apr 2, 2008 1:29:22 PM

  We have a 99 safari. The blower motor resistor is bad (the blower doesn't turn off even with the key out of the ignition). The old resistor had a part number on it from the factory. The part number has changed. We got the new part from the dealer. But they have "upgraded" the part so it does not look like the same thing. The mechanics at the dealer insisted that ... Read More

  You people are aright! My 2001 GMC Safari also had no heat from some outlets.Sometimes they would finally open up.You told me where to look for that tiny plastic vacuum line by the AC unit and where to look on the intake manifold. Sure enough the line was brittle and leaking by the engine.Nappa Auto sells 3' lengths of the plastic tubing(1/8")and the old fittings just pull out.I did cover the ... Read More

  Written by: brantley1 on Aug 9, 2005 5:58:37 PM

  Never heard of such to that extreme. I've had minor electrical glitches like that, but I traced the problem down to a very loose battery connection. I switched to the big battery post adapters that "normal" vehicles use anyway and that solved my electrical problems. With the running lights -- it sounds like a loose connection within the lighting harness to both the lights. Good luck tmoney!

  I'm surprised that the man didn't know about the problem. All of them did the chatter when turning. The fix for it is changing the oil in the transfer case. Check with a GMC dealer and they can do it. GM payed for it during the first 36,000 miles. But I think they make you pay for now. I don't remember if the new oil has to be synthetic or not. ...
