Hey forum members,
I recently bought a 2009 Aveo 5 that had non-functioning A/C system.
Here is what I found:
The A/C compressor would engage (and stay engaged), but none of the pipes were cold. Ok, so time to check the A/C charge to make sure.
I hooked up my Harbor Freight A/C gauges and found that low side was high and the high side was.....low. Basically, there wasn't enough of a pressure difference between the high side and low side to create any meaningful cooling.
So it's either:
1. A bad expansion valve, it's not closing properly and restricting the high side.
2. The compressor has had it and is not pumping well enough to create the pressure that is needed.
Question for the forum members: Are either the expansion valves or compressors known problems with Aveo's? I don't want to do the job twice, but I also don't want to replace parts that don't need it.
