So my A/C went out Friday I did some investigating and the fuses inside the car for the A/C are good. Ater that I saw that the clutch was not engaging so I put direct current to the compressor and it does turn on and it does blow cold air.What other parts can cause the clutch not to engage? I also found no leaks.
1989 Chevrolet Beretta 2.8

Check the pressure, you could be too low and the pressure switch is disengaged. Or the pressure switch is bad.

Not sure on a R12 system... Mine is right out front with three wires on it. It's the line coming right off the condenser on the right front corner of the car.

Thanks 3X00-Modified I found the pressure switch. My GTU has two of them. Online people talk about a relay for the beretta that also go bad. Where would that relay be located?

not sure... there is a relay grouping on the firewall but I'm not sure which one it is. I'd check a haynes book first though and see if it marks it.
