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?
