Broken passenger side mirror?

Hello,
This inoperative mirror can be due to the hit loosening the electrical connector or pinching the wire to the mirror or it could have damaged the motor for the mirror.

The best course of action would to take apart the mirror and inspect the components. First check to see if you have getting power to the mirror.

If you have power to the connector of the mirror but the motor is non functional then likely the motor is bad. Typically you have to replace the mirror assembly when you have a faulty power mirror motor.

Please let me know of any questions.
Thank you.
