Power Mirror Defogger
NOTE:
Heated mirror is controlled by rear window defogger switch. Heated mirror is on whenever rear window defogger is on.
- Mirror should be warm to touch with rear window defogger activated. If mirror is not warm to touch, check fuse No. 12 (10-amp) in junction block, located at left end of instrument panel. Repair short circuit and replace fuse as necessary. Check for battery voltage at mirror harness connector Light Blue/Yellow wire with rear window defogger switch on. If battery voltage does not exist, repair wiring as necessary. See WIRING DIAGRAMS . If battery voltage exists, go to next step.
- Apply voltage to Light Blue/Yellow wire at heated mirror and ground Black wire at heated mirror. Mirror should become warm to touch. If mirror is not warm to touch, remove mirror and test wires for continuity. If no continuity exists, repair wires. If wires are okay, replace mirror. To test defogger switch, see appropriate wiring diagram in REAR WINDOW DEFOGGERS & HEATED MIRRORS - CARAVAN, TOWN & COUNTRY, & VOYAGER article.
