Recently rescued a 98 2wd 4.0 5speed XJ. I've been steadily working through issues and making progress. My next big hurdle is fixing the A/C system. I don't have any experience servicing vehicle A/C systems, but I'm determined to learn. Been going to Youtube academy to figure it out, but with you guys being experts and all, I thought I'd include you in the process. Here's what I've done so far:
- In the cab with the A/C and fan on full blast, I get plenty of air, and the vent positions change as they should, etc. Should be all good inside.
- Under the hood with the engine running and A/C on, I hooked up some manifold gauges and got readings. About 4PSI on the low side, and looks like roughly the same on the high side. Figured I was just basically out of refrigerant.
- Noticed that the compressor wasn't engaging, which I know could be the low pressure switch. I made a jumper to bypass the switch just to see if it would come on. The electric fan comes on like it should, but the compressor clutch doesn't engage at all. Pulley spins freely, but it doesn't grab. I checked that its hooked up, but I haven't probed it for voltage yet.
