Hey all. For awhile I have noticed that my digital exterior temperature gauge flashes when I first start the car. While its flashing, the A/C won't kick in and instead I get blasts of hot air. However, when it quits flashing, anywhere from 15 seconds to 2 minutes, the cool air pours in. Any ideas?

Hmmm...my '93 SSEi began flashing the temp a few months after I bought it in '99, but I wasn't so lucky...mine never stopped flashing, and didn't blow cold air. My compressor had to be replaced (along with the dessicant unit, pressure switch, etc.), then a leak was fixed, and then the radiator-like unit behind the dash had to be replaced, all within 6 months of ownership. It cost me $1,500 and they did the work on several different occasions until they got everything working again.
The digital climate control unit on my '92 and '93 have built-in diagnostics. You press and hold 2 buttons to start the diagnostics, but I don't remember which ones. I can look it up in the shop manual for you if you want. Anyway, the flashing temp might mean that there'* an error code stored. Mine was code 60 or something like that, which meant that it was low on freon.
Good luck with yours...maybe it'* just low on freon or something simple.

Ahhhhhhh The lovely temp flashing. Mine did this for a while, and unfortunately it only blows cold air on rare ocassions. Other than that its Hell on wheels with hot air blowing constantly. According to my dealership they said it was a Door Actuator behind my dash. $450 in Labor only, No parts considering all they have to do is remount the door. Thats gonna be a summer thing for me since I am too lazy to save for that right now.

okay, i had my car scanned. After consulting my GM service manuals, it seems I need to replace my HVAC programmer. Anyone know anything about this? It doesn't sound like its going to be cheap!

Sounds exactly like my problem(*). I was told it was the air mx doors behind the dash as well, but its gonna cost you alot more than $450, the whole dash needs to come out. I'm doing it myself, I just hope once I put the car and dash back together the frekin thing works!!
Did anyone ever persue this further and find a cause / solution ?
