Frequently Asked Questions
Can I replace just the mirror motor?
In most modern vehicles, the mirror motor is integrated into the mirror assembly and the entire unit must be replaced.
Why does my mirror not fold in anymore?
The folding motor may have failed, or the gear mechanism inside the mirror housing may be stripped.
Does this affect side camera or blind spot monitoring?
If the mirror houses a blind spot indicator or camera, a mirror replacement should include those components.
