Q: Q: Ac

asked by on

My ac is blowing, but no cold air. Compressor is engaging. Can the compressor turn and still have faulty parts? High and low pressures are good. I had it checked yesterday for leaks, they didn't find any. The shop wanted to charge an additional fee to check the wiring, I thought it was included in the ac diagnostics. I'm thinking the expansion valve could be bad or a clogged line? What switches or modules would you recommend me checking?
