Sideview mirror motor (their diagnosis) was replaced because I reported that sometimes upon startup the mirrors would randomly travel to the limits of their travel and then start "popping" against the mechanical stops. This action was uninitiated by me.What was the side view mirror motor originally replaced for? I’m not aware of any feature to have the mirrors angle downward in reverse; did you modify the door module calibration with ForScan?
The tilting down in reverse is a function I enabled in Forscan. That function is not the issue in question though. I was using it as an example of how the mirror still acts correctly in some circumstances.
The new issue since the service call is that the mirror loses its angle over 5-8 minutes of driving, and this has only happened since the motor was replaced during the service work. Before the service the mirrors popped randomly, and it was annoying, but the mirrors always went back to their correct position and held their position.
