I have a 1992 Buick LeSabre 3.8L V6. The AC won't cycle. I can't get voltage to the clutch plug. The switch at the back of the compressor shows closed. The low pressure switch shows open. I jumpered the low pressure switch and the radiator fans came on but still no voltage to the clutch plug. What am I missing? Where can I get a schematic for this? The clutch shows a small resistance (300ohms?). The fuse is not blown. Thank You!
Have you used a pressure gauge to determine if there is sufficient refrigerant pressure to engage the compressor?
Have you checked all the fuses?
