Electrical shorts on 12a hvac?
Ok, drove my rex Thursday to work, and for lunch and after work backroad blasts. After my last blast, I decided to get some drive through food. While waiting in line, I turned on the a/c. At that point, the blower quit and no light on a/c or recirc. Ok, I tried several things, and nothing had an effect.
So just now I went out to examine the fuse box, pulled every single fuse and they all looked like new. Stumped, I started the car (started easily even without choke because I forgot to pull choke- I love this car) and the blower and a/c now work perfectly!(?) WTF.
Is there something that would cause this besides a blown fuse? Car is completely stock and in excellent mechanical condition- never wrecked (1985 GS)

The pressure in the AC system may be low enough to trip the circuit-breaker so the compressor pump won't engage at certain ambiant pressures and temperatures. But then again, I don't know much about AC type stuff. Weird problem you've got there. Or maybe it was a one time only fluke, or a loose electrical connection somewhere.

Well, going down the fourlane, I see a train is running alongside, and don't see the front. This road ends by crossing these tracks. I want to SPEED up but the road is blocked by two cars going the exact same speed. I finally get by, but it is too late- I arrive at the crossing just in time to see the train come into view. While waiting for this train to pass, I decide to actually listen to the stereo, and run the a/c- both work perfectly. After the train goes by, I turn off the a/c and leave the blower running. I drive the remaining 15 miles to Bulls Gap. I stop, turn off car and buy beer. On the way back I decide to clean windshield- but the windshiled wipers and fluid spray don't work. And the blower and a/c aren't working either. Everything else works. (?)
I get home, turn off car, then decide to just turn it backl on = EVERYTHING NOW WORKS PERFECTLY. WTF? Anybody have any clues? I don't like the idea of speeding in a sudden shower, and the wipers decide not to work.
