Ac only works when stopped, and compressor engages/cycles erratically.
When the ac is turned on sometimes it'll take 5 minutes for the compressor to even engage. Once it does, the pressures seem pretty good to me. 135 on the low side and 190-200 on the high side at 70-75F. It doesn't cycle like it should though. When I had the gauges hooked up to it it ran nonstop for about 10-15 minutes until I shut it off. I've noticed it cycling normally while stopped a few times, but I didn't have the gauges hooked up.
It doesn't really get cold, just decently cool, and as soon as you start moving it gets warm again.
Any ideas? Electrical? Compressor? Just low on refrigerant?
