QuestionI have a 1999 Grand Cherokee Jeep (limited edition)(V6). I think, there is a problem with its knobs at the AZC, maybe its electrical circuits. I am sure that nothing goes wrong with the gas pressure of AC. It doesn't blow neither warm nor cold air that I adjust, only blowing fixed little bit cool air ( probably 68-69 F)at all times. The fault codes are 01, 05, 08 from self-diagnosis. How to repair this problem?
