I have a 1997 XJ 4.0 Auto 4x4 and I recently replaced everything in the A/C system except the compressor. Holds pressure fine, compressor working perfectly and the readings on the gauges are exactly within spec.
But the air in not COLD. It’s cool, but not cold. This Jeep had great A/C back in the day before I messed with it. I had to replace the heater core so I replaced the evaporator while I was I. There because at the time they were both 19 years old and I didn’t want to have to do that terrible task of pulling the dash off ever again. Turns out I would have to, 2 more times. Second time was to replace the cheap aluminum heater core that failed in 8 months. Third time was last weekend when I pulled it off to check the last culprit in a search for a leak in the A/C system. The evaporator failed. Now I have a new evaporator, new lines, new condenser, new drier, and the original compressor. I drained and filled the compressor with fresh oil before reinstalling, even flushing the old fluid out by rotating the compressor pushing the fluid out and repeatedly refilling. I filled the system with 2 cans of R134a. Pressure reading on the gauges are around 40 low side and about 250 high side. Compressor kicks on instantly and runs without any issue. Electric fan kicks on as always and runs perfect.
I’m at a loss for why this thing is cool, but not cold like it used to be. I used to have to turn the thing off periodically because I got too cold even on 90 degree days here in Georgia.
Any help and guidance would be much a appreciated.
