Hi All, 98 2.5L 2WD XL w/ Auto Trans. On my way home from a camping trip last summer. The AC suddenly cut out and stopped blowing cold. I grabbed a recharge kit on the road but when I hooked it up it said the pressure was good and no charge was needed. I didn't mess with it at the time since it was almost fall.
Now I'm looking into it. On a trip to the salvage hard I grabbed the high and low pressure switches, relays, fuses, etc. The compressor is not engaging so I systematically swapped out each switch, fuse, relay etc. and none of that solved it so I think I can rule those out. I hooked up my AC Pro recharge kit again and it was reading 0 pressure, which I thought was odd since I could definitely hear pressure as the schrader valve engaged when disconnecting the high pressure switch. So I recharged it for about 10 seconds and when I released it was in the middle of the green but compressor clutch still not engaging and only hot air coming out.
I quickly jumpered the low pressure switch and the compressor clutch engaged but it made a bit of a screeching sound. Only jumpered it for a few seconds. About 5 years ago I had a leak in the compressor so I had it replaced, along with the accumulator/drier, orifice tube, o-rings, etc. AC was flushed and filled and worked for 5 years before the sudden cut out. I have a (I think) separate issue with AC diverting to only blow hot air out of the defrost/floor while accelerating but I think that's a separate vacuum related issue.
Anyone have any thoughts on what the issue might be?
