Hey all! It has been 3 years since I last drove my Solstice and I recently brought it up to NC from FL. Thankfully, everything started right up with no fuss. Only thing I noticed is that the a/c is not cold anymore! I checked the low pressure line and the gauge says it is filled, I also remembered to calibrate the HVAC as it had been disconnected from the battery for some time. The clutch on the compressor is not engaging either. What should I attempt prior to looking into replacing the compressor?
