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

INTERMITTENT PARASITIC LOAD PROBLEMS
Intermittent parasitic lad can occur because of a memory
device that does not power down with ignition off. With an
intermittent parasitic load, battery draw can be greater than 1.0 amp.
To find and intermittent problem requires that an ammeter and
Disconnect Tool (J-38758) test switch be connected and left in the
circuit. See Fig. 1. Road test vehicle. After road test, turn ignition
off and remove key.
Monitor the milliamps scale for 15-20 minutes after ignition
is turned off. This allows monitoring memory devices to determine if
they time out and stop drawing memory current. The test switch is
needed to protect ammeter when the vehicles is started.
DIODE CHECK & SOLENOID TEST (GENERAL MOTORS)

CIRCUIT BREAKER
1) Circuit breaker is located in fuse block. On Ram Van and
Ram Wagon, fuse block is located under glove box door. On Ram Pickup,
fuse block is located at extreme left end of instrument panel under
protective cover. On all models, pull circuit breaker outward
slightly, ensuring circuit breaker terminals still contact terminals
in fuse block. Connect negative voltmeter lead to ground. With
positive lead, check each terminal of circuit breaker for voltage.
2) If battery voltage exists at both terminals, circuit
breaker is good. If battery voltage exists at only one terminal,
circuit breaker is defective. Replace circuit breaker. If battery
voltage does not exist at either terminal, check for open or shorted
circuit to fuse box. Repair as necessary.
MOTOR
1) Operate power seat switch to move all 3 seat motors. Seat
should move in all directions. If one or more motors operate, see
POWER SEAT SWITCH. If no motors operate, go to next step.
2) Check circuit breaker in fuse block. See CIRCUIT BREAKER.
If circuit breaker is good, go to next step. If circuit breaker is
faulty, replace circuit breaker and retest system.
3) Remove power seat switch. See POWER SEAT SWITCH under
REMOVAL & INSTALLATION. Check for battery voltage at power supply (Red
wire on Ram Van and Ram Wagon; Red/Light Blue wire on Ram Pickup). If
battery voltage exists, go to next step. If battery voltage does not
exist, repair open in wire.
4) Check for continuity between switch connector ground
circuit (Black wire on Ram Van and Ram Wagon; Black/Orange wire on Ram
Pickup) and ground. If continuity exists, go to next step. If
continuity does not exist, repair open in wire.
5) Test power seat switch. See POWER SEAT SWITCH. Replace
switch as necessary and retest system. If switch tests good, check
wiring harness between switch connector and motor. Repair as
necessary. If wiring is okay, replace defective power seat
adjuster/motors assembly.
POWER SEAT SWITCH
Remove switch from mounting position. See POWER SEAT SWITCH
under REMOVAL & INSTALLATION. Using an ohmmeter, check continuity
between power seat switch terminals as indicated. See POWER SEAT
SWITCH CONTINUITY TEST (RAM PICKUP) or POWER SEAT SWITCH CONTINUITY
TEST (RAM VAN & RAM WAGON) table. See Fig. 1 or 2. If continuity does
not exist as specified, replace switch. If continuity exists as
specified, switch is okay.

1999 ACCESSORIES & EQUIPMENT
CHRY - Power Windows
Caravan, Dakota, Durango, Ram Pickup, Ram Van, Ram Wagon,
Town & Country, & Voyager
DESCRIPTION & OPERATION
A permanent magnet motor moves each of the power windows,
including power vent windows. A positive and negative battery
connection to either of the 2 motor terminals will cause the motor to
rotate in one direction. Reversing current through these same 2
connections will cause the motor to rotate in the opposite direction.
Each individual motor is grounded through the master switch by a wire
attached to the instrument panel reinforcement.
Caravan, Durango, Town & Country and Voyager are equipped
with an Auto Down feature. Drivers window can be lowered without
having to hold the switch in the down position. Auto Down feature can
be activated by pressing down switch past first detent. Caravan, Town
& Country and Voyager have optional power vent windows. Power rear
vent windows are operated by switches mounted in driver's door panel.
NOTE: Power window circuits on Caravan, Town & Country, and Voyager
use Positive Temperature Coefficient (PTC) devices. The PTC
is a specified amperage solid-state resettable fuse. PTCs are
located in junction box behind driver's side of instrument
panel, to left of steering column. To reset PTC, all current
must be removed from PTC for approximately 20 seconds.
ADJUSTMENTS
WINDOWS
Remove door trim panel. See DOOR TRIM PANEL under REMOVAL &
INSTALLATION. Loosen bolts holding window to regulator. Raise window
fully, seating window in frame. Tighten bolts. Install door trim
panel.
TROUBLE SHOOTING
CARAVAN, TOWN & COUNTRY, & VOYAGER
Inspect both No. 8 and 9 (9-amp) PTCs in junction block.
Junction block is located under left side of instrument panel.
* Inspect fuse No. 23 (40-amp) in Power Distribution Center
(PDC). PDC is located on left side of engine compartment.
* Inspect ground at instrument panel left side cowl.
DAKOTA & DURANGO
Inspect circuit breaker No. 20 (20-amp on Dakota, 25-amp on
Durango) in fuse block. Fuse block is located on left end of
instrument panel.
* Inspect fuse No. 9 (40-amp) in Power Distribution Center
(PDC). PDC is located in left front corner of engine
