Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I am Mike, welcome. I'm reviewing your question.
The power exterior mirrors are controlled by the DSM and are operational all the time, whether the ignition switch is on or off. Using the power exterior mirror switch, the driver can adjust the driver and passenger exterior mirrors four ways.
With that done said, it appears as though it's a faulty power exterior mirror switch.
