i have a 98 blazer LT with the auto climate control.

i do have control of fan speed.
i dont have control of temperature
i dont have control of vents
the a/c compressor does not turn on when i select it to

i have tried 3 different panels, and have done what i *think* is the learn procedure.

anyone have any simmilar problems? what did you find to be wrong? ive been playing with this issue for a few weeks now with no luck.

 

nobody?

 

wow. i must have a pretty oddball issue here.

 

Maybe the same issue i had. Check my thread. Also click on the link thats in my thread regarding where all the vaccum lines run too.

Maybe broken vaccum lines.

 

ok, i have temp control and my a/c goes on and off now as it should. however i still am having trouble with the vacuum doors. does anyone have a diagram handy? maybe a little advice?
