Hi!!! I have an issue with an 05 equinox.a/c quit working,noticed fans weren't coming on with a/c,checked to make sure fans worked and cam on with temp and they checked out.Replaced pressure switch beside the pump but still no luck.Noticed low side was high,let some refrigerant out,still no a/c,compressor is running but no ac.Ordered a control valve for the compressor but haven't installed it yet,was wondering if maybe it could be expansion valve. Any ideas?

No. 1-1


could be that, but just wildly guessing by letting refrigerant out is not a good thing to do. Guessing is foolhardy, if pressure was high and you didn't add refrigerant, now it will be low on refrigerant. Pray it's just the bad expansion or orifice tube
