Hi, I was looking for some assistance with my car. I have a 2006 Pontiac G6 GT 3.5L and recently the AC stopped blowing cold air. There was a leak in the low pressure maintenance valve which turned out to be a bad valve stem. We replaced that and brought it to have it serviced. They cycled the whole AC system and are saying we need a new compressor. Now for the odd part: the compressor still kicks on and spins and the system is full of coolant, yet still no cold air. Any help on this matter would be greatly appreciated, I live in florida so as many may know AC is a must.
