Good afternoon all, I have an 03 Tahoe with rear air and the auto climate control. My issue is this. The compressor only works intermittently. It has been replaced due to the slugging issue. However, I still have the compressor kicking on and off. On 110 degree days, that sucks. I can come up with two possible culprits. The pressure switch and the evaporator. The pressure switch or expansion valve due to the fact that it (by a seat of the pants feeling) does not keep a constant pressure, causing it to cycle on and off for varying periods. It could be 5 minutes, it could be 50 minutes. Based on my usderstanding, the system should operate at a constant pressure. If this switch goes bad, the system will build pressure and operate. When the pressure bleeds off, it will kick off to rebuild pressure. The evaporator due to the fact that while it cycles off, the climate control system increases air flow, but the air is moist. I live in the desert. What are your thoughts or experiences with this? Thank you in advance.
