Dodge Ram Truck 1500-2500-3500. Manual — part 491
POWER WINDOW MOTOR TEST
If the power window motor is receiving proper current and ground and does not operate, proceed with motor test.
1. Remove front door trim panel as necessary to gain access to power window motor wire connector (Refer to 23
- BODY/DOOR - FRONT/TRIM PANEL - REMOVAL).
2. Disconnect power window motor wire connector from door harness.
3. Using two jumper wires, connect one to a battery (+) source and the other to a good ground (-).
4. Connect the Negative (-) jumper probe to one of the motor connector terminals.
5. Momentarily touch the Positive (+) jumper probe to the other motor connector terminal.
When positive probe is connected the motor should rotate in one direction to either move window up or down. If
window is all the way up or down the motor will grunt and the inner door panel will flex when actuated in that one
direction.
6. Reverse jumper probes at the motor connector terminals and window should now move in opposite direction. If
window does not move or grunt, replace the motor.
If window moved completely up or down, reverse the jumper probes and cycle window to the opposite position to
verify full operation.
If motor grunts and does not move, verify that regulator is not binding.
SWITCH - WINDOW
DIAGNOSIS AND TESTING
WINDOW SWITCH
The Light-Emitting Diode (LED) illumination lamps for all of the power window and lock switch and bezel unit switch
paddles receive battery current through the power window circuit breaker in the junction block. If all of the LEDs are
inoperative in both the power window and lock switch units and the power windows are inoperative, (Refer to 8 -
ELECTRICAL/POWER WINDOWS - DIAGNOSIS AND TESTING). If the power windows operate, but any or all of
the LEDs are inoperative, the power window and lock switch units with the inoperative LED(s) is faulty and must be
replaced. For complete circuit diagrams, refer to the appropriate wiring information.
1. Check the fuse in the Integrated Power Module (IPM) and the circuit breaker located near the park brake pedal.
If OK, go to Step 2. If not OK, replace the faulty fuse or circuit breaker.
2. Turn the ignition switch to the On position. Check for battery voltage at the fuse in the Integrated Power Module
(IPM). If OK, turn the ignition switch to the Off position and go to Step 3. If not OK, check circuit breaker and
repair the circuit to the ignition switch as required.
3. Disconnect and isolate the battery negative cable. Remove the power window switch unit from the door trim
panel (passenger doors). The drivers door switch is included with the window/lock switch (Refer to 8 - ELEC-
TRICAL/POWER LOCKS/DOOR MODULE - DIAGNOSIS AND TESTING) for service procedures. Unplug the
wire harness connector from the switch unit.
4. Test the power window switch continuity. See the Power Window Switch Continuity charts to determine if the
continuity is correct in the Off, Up and Down switch positions. If OK, (Refer to 8 - ELECTRICAL/POWER WIN-
DOWS - DIAGNOSIS AND TESTING). If not OK, replace the faulty switch.
