Yet another wonderful trip to the Chev dealership today. I needed to replace the CAF now that I am using AC more... it makes the mildew smell while running. Since I have replaced these in a number of vehicles before I went up to the Parts counter and of course they recognize me because I am there $o much. They look up the VIN and sell me a square filter.. makes sense so far. Get home drop the glove box and begin to look around for a replacement assembly .....not there... I resort to google and a video that shows it sliding out on a tray with ease. Well not for the 2011 I guess. No in fact the square bod that SHOULD house a air filter is in fact when split by unscrewing the top and bottom is the AC CONDENSER. I button it all up and make sure it is blowing cold again.. it is and proceed up to ask about another placement or at least a clue. Well they tell me if I would like to check it in they will install it for me at a discounted rate of $ 60.00 plus filter. They tell me I may have the wrong filter so they will use there part # to get the right one..........when will this madness end? Tires, locks,clocks,lights and keys..... it's not even 4 years old????? Can anyone help me please????
