1994 Oldsmobile Bravada 6 cyl All Wheel Drive Automatic

My ac compressor clutch won't engage on my 94 bravada. I think it is the relay but don't know where it is located. Can you tell me please.

Would require some rewiring. Easiest way is to simply swap the relay with another same sized relay on the vehicle.

Any idea which one to swap it with? The other relays I see are a lot bigger then the one in question. Should like a good idea I just don't know which one to swap it with.
