1991 4.0L AW4 4x4
Looking for some ideas on what to be checking and testing so I can get my AC going for summer. Prior to having the system looked at, it blew warm air.
Went to a guy that charges R12 systems and he tried to charge the system but said that the AC compressor wasn't taking in the freon and more than likely it was toast. So I come back home and SEARCHED. I tested the clutch by giving it direct 12 volts and it engages fine. With the jeep and the AC ON, I got a multimeter and tested to see if I was getting 12v at the clutch wire but I WASNT. So then I swapped the AC relay with the starter relay (known to be good) to see if that did anything and still no juice going to the AC clutch wire. Any other ideas for testing? NOTE: The system did have a small charge in it before the AC guy evacuated it. Thanks
