  2. Check DOME fuse (7.5-amp). DOME fuse is located in fuse/relay box at driver's side of instrument panel. See Figure. If DOME fuse is okay, go to next step. If DOME fuse is defective, replace fuse and repair wiring harness or electrical connector on wiring circuit as necessary and recheck vanity light operation.

Using ohmmeter, check that no continuity exists between electrical terminals on vanity light with mirror cover closed to the OFF position and that continuity exists with mirror cover opened to the ON position. If operation is as specified, reinstall electrical connector. Go to next step. If operation is not as specified, replace vanity light and recheck vanity light operation.
