2008 Masarati Gran Tourismo Replaced A/C condenser and Compressor. Pully was frozen on compressor. Charged compressor with R134a. Turned. A/c on and not working. Blower comes on but does not blow cold. Ideas ?? All parts replaced were ffactory any answer yet ??
Thank you for taking time to reply. I was remiss in not stating that we did check the fuses and relays and all checked out ok. The customer said that he was driving in Arizona when the A/C stopped working, it made grinding noise and he smelled something burning. We inspected the compressor and it had the pulley very loose and when we spun it, it did indeed have a grinding noise , I guess with that said, I will have to trace the wiring for signs of burnt wiring, we did not observe any signs when we were replacing the compressor All fuses and relays check out ok.
