A/C help please
 

New guy here, I have a 1990 coupe, The a/c does not work,just stopped. It has got 0 volts at either switch in the lines under the hood. Freon is full and if you jump the compressor it will cool. The controller in the dash seems to be working but I cannot find the a/c relay. Thoughts anyone? Thanks Gus

a/c relay is under dash on driver side there are 4 relays there frm left to right should be , ac clutch relay,start enable relay, amp relay,fuel pump#2 relay. if you have a digital ac heat unit thrr i a wy to enter diagnostic mode to check for problems .

Thanks , After I have taken the consol and both sides of the dash apart and countless hours I give up and took it to an A/C shop. The guy was honest and told me he had been running from Vettes for 20 years.(didn't like them) He ask what all I had done and said take it home and remove the negitive cable for 5 minutes. I have air,and now just have to put everything back, gus
