The vanity mirror light on the passenger side (the side where my wife and children sit....lol ) is not working, appears as though it's not getting electrical power. I believe some way the switch in the visor that activates the light may be faulty or broken; seems as though both visor's vanity lights use the same fuse so it must not be the fuse, because the light works on the driver side (my carefully cared for side). Any ideas on how to fix this vanity light?
