I will have to check the cables for continuity but to do that I'll have to drop the door card. Not done that yet so will have to read up how to do it.
I do have a spare mirror mount complete with cables so if I have a cable problem I should be OK.
After that it could only be the controller.

I have checked the continuity on my glass and found that it is ok as well. I have already tried replacing the door electronics module and that didn't solve the problem.

The only issue i can think of now is a wiring problem in the wing mirror harness as my Side Assist light on that side is also having an issue.. Might be a grounding problem. I will next try to remove the Side Assist light and check if that's the culprit itself.
