oldsmobile auroua a/c problem

Unread post by jpruntich » Wed Mar 16, 2016 11:03 pm

I am looking for a wiring diagram for a 2001 oldsmobile auroua 3.5L......for the a/c system.....it is fully charged and there is no compressor engagement I checked the fuse and I swapped the relay with the horn relay which is exactly the same relay.....no go.....so I unplugged the compressor with the car running and a/c on high and found I have power but no ground......I would like to trace the ground wire to see where it goes and the problem is....thanks in advance for any help
