DIAGRAMS.
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.
