Thanks for your reply. I had Cataract surgery last week and can't bend down until next week. So, I am, doling a little desk debugging for now. If the climate control amp is bad, would the AC clutch come on? Or would hot air override the cool air? I assume the CC amp sends a message to the Servo to direct hot water or no water or cool air to the cabin. is this correct? If not, you will not make me angry to say...you or wrong...I welcome it.
