Hey All,
I was driving along the highway through Utah (103-108 degrees) and the AC stopped blowing cold and never came back--it's been out for 3 days.
Here's what I know:
1. The cabin/blower fan, as well as the AC, Max AC lights all work.
2. The Condenser fan outside works fine when the AC is "on" inside the car, but the clutch never engages the compressor pulley.
3. I've swapped the relays--no change in behavior.
4. Under hood fuse 20 and under dash fuse 36 are all intact.
5. The clutch spins freely without drag--the gap is appropriately between 0.35 and 0.65mm
6. The pulley wheel spins without issue when the engine is on.
I was thinking I need to replace the clutch/pulley/coil combo, but here's the kicker...
I went to AutoZone today, borrowed a Low side pressure gauge. The pressure was solidly in the Red (more than half way between 60 and 150PSI) with 2 separate gauges with several measurements. The AutoZone tech vented the Low side line into the air, via the gauge, and the reading returned to the same pressure (in ~5-10 seconds) once the valve was released again.
I'm stumped now, but am fortunately in a cooler climate and can wait for a bit...buuuut I would like to get it resolved. Thoughts??
