Per the information that gilly supplied. I using the power mirror controls tilted the mirror down and out to look for the power wires.
And there it was two wires for the heated mirror. But the problem was that one of the wires were not connected.
It turned out the wire was to short to make the connection when the mirror is in the down and out position. It was probally attached at the plant but when I adjusted the mirror the wire was to short and was pulled from the socket.
And why was the wire to short?? It was an assembly error. When the assembly the mirror assembly they had the wire wedged between two assembly parts.
I using tweazers and a large unfolded paper clip unwedged the wire and reconnected it. It took me over an hour (wanted to be careful).
I verified the operations of the mirror putting an ice bag over the mirror housing and turning the key to the on position (the engin does not have to be running) and I felt the mirror heating up with the back of my nuckles.
I think we could put finaly close this case.
thanks again Gilly to to you all.
