GMC Safari/Chevy Astro Heating / Cooling
I have a '94 Astro bought used a year ago. Took it on a 3000 mile round trip last summer with no problem. Now has 45K. A week ago suddenly there was a smell (intermittent) coming through the vents from the engine when the fan is in the "VENT" position. Does NOT happen with AC on. Oil, trans, coolant levels all OK. Thought maybe it was a refrigerant leak on the engine. Took it to a Chevy dealer, who could not duplicate the condition. (Told ya it was intermittent.) NOW it appears that maybe the smell wasn't coming through the vents (though I could have sworn it was), because I caught a little wisp of smoke coming from the fan switch. Dealer's electrical expert says nothing to worry about, could just be dust on the switch. This is a reputable dealership that says they try to avoid unnecessary parts replacement & expenses. I'd like to resolve this before taking another long trip next month and am strongly leaning toward replacing the switch, anyway. Feedback? Similar experiences?

I, on the other hand, am having to replace the compressor on the wifes '95 model. It still will freeze your cheeks off, even here in Texas, but the internal bearing, not the pulley end, is going bad and the thing sounds like it is about to come apart.

what I might be able to do before hauling it in to the dealer. Can anyone tell me what could be the problem. I'm not certain if it it mechanically or electrically controlled, a linkage or switch issue and would like some direction before tearing into the dash.
i have a 2000 safari. air only comes though the defroster for the windshield and at your feet
I have the same problem on my '98 Safari. Can you tell me more about where to locate this vacuum hose? Is it accessible from inside with the doghouse removed? What make you decide not to replace it with new parts?
I have got hold of a Haynes Repair Manual but it's no help at all. I too like to investigate more to decide if I have to take the dash out. Thank in advance for your advice!
When the motor came out I dissected it expecting to find worn or hung brushes. I had neither! Everything looked fine. I had tested and found voltage to the unit before removing it, but now suspect that maybe the voltage that registered on my digital Radio Shack cheapie maybe didn't have enough amps to turn the motor.
Any ideas?
My directional air controller has failed as well. But from reading previous fixed I'm going to have to look at the vacuum line.
My A/C left sometime last year and I can't tell if the clutch is engaging or not. It worked fine always good and cold until that point. I would appreciate some advice on how to begin trouble shooting that system.
Why do I love her with all these problems? Unlike my wife, I've had her since new, and she's proved WAY more reliable and predictable.
Thx in advance for any and all advice.
It was unseasonably warm last saturday,over 90 degree F. We usually don't get this weather until way into July. Now, DW is threatening to file for divorce if I don't get A/C to come out from the dash outlet. :mad:
Anyway, thank cob for the tip.
I found it. It was broken in two places and lying on top of the thermostat housing. There's actually a flat spot on it resulted either from heat or rubbing against some moving parts. Without your descriptive & helpful explanation, I'd never suspect this stiff dingy 1/8" hose is a vacuum hose. I was looking for a 1/4" flexible rubber hose all along. BTW, did you buy the replacement hose from auto parts store in bulk or you have to get it from the dealer.
Thank you in advance!!!
