no heat or a/c
 
I have no a/c or heat in the car, the blower blows, and the fans do not come on when the a/c is turned on. All the fuses are check and relay is good, any other ideas?? I just bought this car so i don't know when the last time it worked.

does any air blow out of the vents?

Get a volt meter, turn on the a/c. Unplug the electrical connector to each fan and see if there is 12V across the pins.

yea i was going to do that tomorrow my meter is at work, i know they do work tho, if the car sits long enough they will come on from the engine getting hot. Does anyone have the wire diagram for the compressor?

The online manuals thread in the DIY section has a 94 shop manual that you can download from the spooner link I posted. That will have a wiring diagram. You want to look at the KH model.

You still didn't answer if air blows through the vents?

Also, does the compressor clutch engage with the compressor pulley? You should check that you get 12V to the red wire going to the compressor.

So like PA asked ,,,,,,,,,,,,does that mean that you got air blowing from the dash vents??? that answer would help a lot to diagnose your issue

can you add year and model in your sig??? 2 or 4 door, at or 5sp etc, etc
