I took my truck to the dealer one time and mentioned to them that my AC had stopped blowing cold air. The one guy I talked to said it was probably the compressor and that the part wasn't covered under warranty and I would have to pay out of pocket to have it fixed. Needless to say, I told the guy never mind and left it as is since the weather at the time wasn't too bad. Well now, we're starting to get into the scorching hot temps of summer here in TX and phuk that shit!! I need some AC!! So I called the dealer again today and was told by another service guy that my truck was still under the bumper to bumper warranty and the repair would be covered. Hearing this great news I proceeded to make an appointment for this Thursday, first thing in the morning to drop it off.
So I'm guessing that depending on who you talk to at the dealership, and the mileage on your truck, they will in fact cover the cost and repair under warranty. Granted, I don't think I should have had to speak or call multiple times for the same issue but in the end, GM is fixing it and covering the cost so I'm good with that.
Here's a pic of where my condenser leaked from. It was more noticeable yesterday before it rained over here. You can still see on the side where it kind of looks "wet".
