Ok so I finally had to start using my AC in my 07 and low and behold the passenger side blows heat instead! I checked all of the normal stuff like pass climate control etc but that didnt fix it. Dropped it off at the Dealership Monday night, they called today to tell me they had to call Chevy Master Tech to see what the problem is, they replaced the acctuator (sp) but that didnt help. Anyone else heard of or had this issue??? Im going to pick up the rental tonight because they said it would be at least another 3 days so everyone cross your fingers that its not a peanut car, i explicitly told him no PEANUTS!
