I have a 94 Camaro......3.4L V6, standard transmission.

I know my ac needs to be charged cause it don't blow cold, but, it seems to be stuck on the defrost setting, regardless of where you set the control. I know it works off of vacuum, but, I can't find the bad one.....if there is a bad one.

Anyone have any clues, hints and tips for me to figure this one out????

Thanks all of you

 

check the ac relay. have it scanned for trouble codes. ac should be throwing codes.

 

Vacuum line was off u nder the hood.......now all I have to do is find a AC compressor clutch and all SHOULD be well. I hope so......this car gets hot inside without cold air

 

ac pump is under the power stearing pump. ac clutch is on the ac pump.
