Symptoms: A/C has gone in and out over the last week (mostly out). Compressor is not engaging. Refrigerant is full.
Here's what I've done:
I have replaced the low pressure cycling switch.
I have recharged the system.
I have replaced every o-ring that I can get to.
Here's what I've tested:
I powered the compressor with a small 12v battery. Compressor worked fine and allowed me to recharge the system correctly.
I've tested the low pressure cycling switch for continuity past the connector. Switch and connector are fine. I do not get 12v on this wire when I turn on the A/C.
I've tested the high pressure sensor. Reference (5v), signal (1.3v), ground (good). Voltages are static when A/C is on or off.
The fuses and relay are fine.
I do not know how to test the climate control unit.
How would you proceed?
