How do I replace a light bulb in a 2001 Expedition turn signal mirror. Can anyone help?

 

Good question. Ive never had to replace one. Just looking at mine, and it appears you would have to remove the rear cover to access it. I have no idea what bulb it may use. To release the tabs for the rear cover you have to get behind the mirror glass, which is tricky. Proceed with caution is my best suggestion at this point. If I had one burned out I would experiment with it. As it is they are both working so Im too chicken of breaking something needlessly. Let us know how you do.
