Re: 2007 Silverado A/C wont get cold after sitting for two months
Have you looked at the compressor to see if the clutch is actually engaging? Also, if it is engaging and you still arent getting cold air out, the blend door could be malfunctioning. I think it uses a small servo motor to control the amount of opening between heat and A/C.
