#999 of 1972 1999 Chevy Astro Air cond. problem,
Aug 05, 2005 (10:25 am)
Any advice would be appreciated. We no longer have cold air coming from the front vents of our Astro. It blows cold in the rear. As we start up, the air seems to be cool but then looses all cold and just blows out hot in front. Rear stays cold. . Could there be a blocked vent or something similar. There is condensation appearing on the ground in the rear left side. but not the front at all All blowers work.. Our car expertise is limited so please keep it simple in wording.

I don't have rear A/C on my '98 but with the help of the forum, I have solved a mulfunction dash HVAC vent control problem. There are lots of recent discussions on this topic. Do a search on tkw, cob and 97expreeso's posts, you'll probably find the answer. There's also a post on Rear A/C that may also applicable here. Good luck with your search!

read message number 969... as for the relay, it should be located under the hood on the passenger side, if you look near the back where the rear of the hood will sit when closed you should see three relays, the pump relay is the one closese to the passenger side fender.

I have 3 problems with my 1999 GMC Safari. First problem is the daytime running lights works for a week or two then goes out for a month then comes back. Next problem is that 2 weeks ago the radio went out no power at all about 30 minutes after that the windows stopped working. The windows are all the way down on both sides and will not come up. I have checked the fuses and as far as I can tell none are blown.
Help and Thanks in Advance

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!

The alternator is easy to change. It takes longer to get the doghouse off to get access to the back side of the alternator. You can replace it without taking the dog house off. Once you get the serpentine belt off I believe there was 2 or 3 bolts holding the alternator on. I changed mine 2 years ago. What I do remember is there is a large wire harness connected to it and a small single wire. I did not see the single wire from the front and when I yanked on the alternator to remove it I broke the small wire. Knowing that there are 2 harnesses on it you should be able to remove it without taking off the dog house, good luck.

I was told that there is a valve under the hood on the a/c lines that has a black cap on it. You are supposed to be able to turn it with a screw driver. I have something different on my 97 since it is an aftermarket unit from the conversion company. Anyhow this valve controls the cooling cycle between front and rear and sounds like it is stuck on the rear setting. I was told to have someone sit in the van while it is running and turn the rear air on and off while someone else taps the valve under the hood to get it unstuck. It may or may not work but it is a free fix. Let me know if it works for you.

Assuming you have the composite Headlamps, here's the instruction:
Open the hood. Remove the sidemarker/turn signal lamp by removing two screws. Remove the corner reflector by removing the screw behind it. Remove the headlamp assembly by removing 3 screws. Replace bulb from behind. Caution: do not touch halogen bulb with bare hand.
