Hey everyone me again. I was wondering,my climate control is not working at all, no heat/air. I can feel that there is heat bellowing through the defrost vents, but no fan control(as in no fan),the lights on the unit do not light up,nor can I hear the vents switching from floor to dash,or defrost. All three componets have power going to them, what I was wondering(before I buy a new unit)was is there a ground wire that could be broken, would there be one ground for the 3 units or 3. I have probably asked this question already in the past but where can I get the proper manual to help guide me through self repair. Thanks a million for all of your help. Hope everyone has a great Thanksgiving
