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.
Caravan, Town & Country, & Voyager
1) 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. If battery voltage exists, go to next step.

2) 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
1) 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.
2) If system does not operate as described, go to next step.
Illuminated indicator light means only that voltage exists at heated
mirror relay.
3) 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.
REMOVAL & INSTALLATION
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
