Wife said AC took a while to get cold. This past weekend I checked it out and it was cooler on right side than left. This appears to be like a 210 does when it is low on refrigerant. I recovered the system and it was about 1/2 lb low. Recharged it and it was cooling great. I was out of town and she has been driving it all week and it was fine. Got home today and we went to town and it is suddenly not cooling at all. Worked fine yesterday she said. I will say before I did the recharge I noticed it would blow hot, then all the sudden start cooling again. I just figured it might be doing it because it was a little low. Also the last time I was in it before I did the recharge I noticed it would cool, then start blowing hot and suddenly start blowing cold again.

I just hooked it up to SDS and it shows its calling for compressor, nothing locking it out like low pressure. No error codes. Pressure shows 10 bar with or without it calling for compressor. With this compressor it turns all the time so you can't tell if its engaged or not. I guess tomorrow I will have to run thru the tests which appears to be testing resistance at one of the plugs on the back of the acc panel, then go from there. Is there a common failure on these it could be? Looking up parts it appears expansion valve might be electronic? Maybe compressor died?
