Resolved Question:

i have a 1992 corvette LT1 and the A/C compressor is not turning on. is there a way to test it? are there any other fuses other than the #2 fuse in the normal cluster that would affect it?

There are many things that will prevent the compressor from coming on. It's controlled by the PCM and the PCM monitors various switches and sensors and will not turn it on until it is satisfied with all of them.

Here is the wiring diagram that shows everything in the circuit.

Reply to Chevy man's Post: so is there any test that i can try to find where it isn't working right? i already tried a multimeter at the plug to it, and there is no power. is the cluch relay a relay under the hood or in the actual compressor. Just trying to get a little more answer to the original question, than "it could be many things".

That's why I gave you wiring diagram. The diagram needs to be followed and all circuits tested to find a failure.
