Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi thanks for using the site. Unfortunately this is rarely due to the actual light going out and is normally an internal part of the mirror circuit board wearing out. Unless you are a trained in circuit board repair, I recommend replacing the entire mirror AFTER you inspect that no wires are loose to the connector on the back side of the mirror. I would recommend an online site to save money instead of the dealership. Do you have any further questions?
