I drove my car home and parked it for 30 mins, the air had been working fine. I got in and started it up, and the air wouldnt blow cold. I checked and the A/C clutch wasnt enaging. I jumped the low pressure switch, and the only thing it did was raise the engine RPM. Removed the jumper and the RPM lowered. Checked the system and its at the proper pressure. So I used a meter and checked the connector going to the compressor. I am getting 13 volts to the connector when the a/c is turned on. However, when I plug the connector in, the clutch does not engage. So I jumped the compressor to the battery. The clutch engages and the car blows cold air. So, I have 13 volts at the connector, no clutch engagement and if I provide power from the battery then the clutch engages. If I run leads from the connector to the compressor, it wont engage. So now I am lost. Oh, when I run the leads from the connector to the compressor, it seems to be pulling.5 amps, when I run the leads from the compressor to the battery, it seems to be pulling 4 amps.
I appreciate any help you guys can offer!
