Hello everyone! I am new to this forum but not new to using forums.

I need a little help in finding a wiring diagram for a 1994 chevy 1500 350. My problem is with the A/C and I made several checks and I am unable to find the problem. I checked the fuse and the clutch on the compressor and it engages when applying external power. I also checked the low side pressure switch and have full continuity but have no power to the compressor clutch plug. I replaced the relay with no joy. Anyone have a wiring diagram so I can track it down?

Gus
