Location of Air Conditioning Relay
 

I have a 94 corvette, would like to know the location of the air conditioning relay. Yes, the ac is fully charged, but the ac compressor clutch is not engaging. The high and low switches work, I am an ac mechanic, but I can't find any manuals for the air conditioning unit. If you can think of any else it could be beside the air conditioning relay, please let me know, but I would still like to know the location of the relay for future use. Thanks for helping guys, I appreciate any help. Remember corvette is the #1 car.
