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

COMPONENT TESTS
CIRCUIT BREAKER
Dakota, Durango, Ram Pickup, Ram Van & Ram Wagon
1) Locate circuit breaker for power window system. See
TROUBLE SHOOTING. Pull circuit breaker out slightly, but ensure
circuit breaker terminals still contact terminals in fuse block.
2) Connect voltmeter negative lead to ground. Using voltmeter
positive lead, check both terminals of circuit breaker for battery
voltage. If voltmeter indicates battery voltage at both terminals,
circuit breaker is okay.
3) If voltmeter indicates battery voltage at one terminal
only, replace faulty circuit breaker. If voltmeter indicates no
voltage at either terminal, check for an open or shorted circuit to
circuit breaker. Repair as necessary and recheck system operation.
VENT WINDOW MOTOR
Caravan, Town & Country, & Voyager
1) Remove "D" pillar trim panel. See "D" PILLAR TRIM PANEL
under REMOVAL & INSTALLATION. Disconnect vent window motor connector.
Using jumper wires, apply battery voltage to vent window motor
terminals. Motor should rotate in one direction, moving window open or
closed. If window is in full closed or open position, no movement will
be observed and motor will make a grunting noise.
2) Reverse battery leads. Window should move in opposite
direction. If window does not move or window does not make a grunting
noise, replace vent window motor. If window moved completely open and
closed, motor should be reversed one more time to complete a full
window movement inspection.
3) If motor grunts and window does not move, remove motor
assembly. Check window motor crank for binding. Repair as necessary.
Recheck window operation. If window moves, check power window switch
continuity. See POWER WINDOW SWITCH. Replace switch as necessary. If
window switch is okay, check for open circuit between window motor and
window switch. See WIRING DIAGRAMS. Repair as necessary.
