The vehicle is giving a code that the out side temp censor and inside temp censor is defaulted we change both censors and problem is still the codes are the same! Also it's saying the part that control the outside air meaning the door that opens and close in the unit is defaulting also... (Forgot the name of that part) What do you suggest now?
So I want to start by saying that nothing is 100% when it comes to online diagnosis, however I had a similar situation and I may have something you can check on to possibly resolve the issue for almost $0. The issue I had (2006 GMC yukon denali xl 6.0l) with this is located in a wiring harness under your left foot in the drivers front seat area. When you locate it under the carpet you should notice a black/burnt place in the connector. The wires need to be removed, stripped, and rejoined. This only takes about 30 minutes if you have everything on hand, but ended up costing me about $400 in diagnostic fees and also a new $279 A/C compressor. This will also resolve an issue were the front A/C may work, but the rear does not. Hope this helps someone else.~J
