this is getting just ugly :(
I took apart the unit. cleaned off the connections and tested them...no change in its behavior. then i said to myself.. self, check the back of the unit'* connection.
The female end (on the climate unit) has a burnt/char on one of the little contacts. Like if anyone has seen a copper pipe that'* aged, thats the look.
Coming from the car, that plug, has the same exact mark on the corrisponding connector. All of the other like 32 contacts are bright gold and looking normal
this is a no good very bad day.
