AUTOMATIC DAY/NIGHT INSIDE MIRROR
- Turn ignition switch to ON position with transmission in Neutral or Park. Place mirror switch in ON position (switch LED illuminated). Cover forward facing sensor with a dark cloth or tape to exclude any ambient light. (Scheme 6)
- Shine a light into rear-facing sensor. Observe whether or not mirror darkens. With mirror darkened, place transmission in Reverse. Mirror should return to normal. If conditions of steps 1) and 2) are met, mirror is operating correctly. If conditions are not met, go to next step.
- Turn ignition on. Check for battery voltage at fuse No. 11 in junction block. If battery voltage exists on both sides of fuse, go to next step. If battery voltage does not exist, repair circuit to junction block. See «WIRING DIAGRAMS»(ref-149725-S07694065152002102100000). If fuse is blown, repair short circuit and replace fuse.
- Check for battery voltage at day/night mirror wire connector terminal No. 1 (Dark Blue/White wire). If battery voltage exists, go to next step. If battery voltage does not exist, repair open circuit between mirror and junction block.
- Check for continuity between ground and day/night mirror wire connector terminal No. 2 (Black wire). If continuity exists, go to next step. If continuity does not exist, repair open ground circuit.
- Check for battery voltage at day/night mirror wire connector terminal No. 3 (Violet/Black wire) with transmission in Reverse. If battery voltage exists, replace mirror. If battery voltage does not exist, check back-up light circuit. See «WIRING DIAGRAMS»(ref-149725-S07694065152002102100000).

Caravan, Town & Country, & Voyager
Disconnect harness connector from mirror and headlight switch. Using 2 jumper wires, connect one jumper to a 12-volt source and the other jumper wire to a good ground. Connect other end of jumper wires to specified switch terminals as specified. See POWER MIRROR MOTOR TEST (CARAVAN, TOWN & COUNTRY, & VOYAGER) table. If mirror operation is not as specified, check for open or short circuit between switch and power mirror. Repair as necessary. If wiring harness is okay, replace mirror assembly as necessary.

Remove switch and disconnect wiring connector. See POWER MIRROR SWITCH under REMOVAL & INSTALLATION. Using an ohmmeter, check continuity between power mirror switch terminals with switch in appropriate position. See POWER MIRROR SWITCH CONTINUITY TEST (CARAVAN, TOWN & COUNTRY, & VOYAGER) table. (Scheme 7) If results differ from table, replace switch.

POWER MIRROR DEFOGGER
Note. On Caravan, Town & Country and Voyager, 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. 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»(ref-149725-S07694065152002102100000) . 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 article.
Note. On Ram Pickup, heated mirror is controlled by mirror defogger switch.
Ram Pickup
- Turn ignition on. While watching instrument panel voltmeter, turn heated mirror switch on. Voltmeter needle should deflect. With heated mirror on, mirror should be warm to touch after 3-4 minutes. If system operates as described, system is okay at this time.
- If system does not operate as described, go to next step. Illuminated indicator light means only that voltage exists at heated mirror relay.
- Ensure ignition is on. Check fuses in Power Distribution Center (PDC) and junction block. Ensure fuses are fully seated and connections are secure. If mirrors are still inoperative, problem is in heated mirror control, mirror heating grid and/or heated mirror harness or connectors. If turning switch on causes a large deflection in instrument panel voltmeter, check for a short circuit in system. Repair as necessary.
