Power Windows - Service Information: Other Dodge Nitro I

WINDOW SWITCH

The power window switches control the battery and ground feeds to the power window motors. Both of the rear door power window switches receive their battery and ground feeds through the circuitry of the front window switch. When the power window lockout switch is in the Lock position, the battery feed for the rear door window switches is interrupted.

WINDOW MOTOR

Front door window lift motors use permanent type magnets. The B+ and ground applied at the motor terminal pins will cause the motor to rotate in one direction. Reversing current through the motor terminals will cause the motor to rotate in the opposite direction.

Refer to POWER WINDOWS wiring information.

STANDARD PROCEDURE-EXPRESS WINDOWS

Anytime the battery is disconnected or in a run down/low voltage state, the auto-up (express) windows must be calibrated.

To calibrate the auto-express feature, perform the following

1. Turn the Ignition to the Run position.
2. Using the scan tool, perform an ECU reset.
3. Position the window at the midpoint of travel.
4. Move the driver side front window upward until the window stalls in the full up position. Allow the window motor to stall for at least 2 seconds before releasing the switch.
5. Move the driver side front window downward until the window stalls in the full down position. Allow the window motor to stall for at least 2 second before releasing the switch.
6. Repeat steps 3, 4 and 5 for the passenger side front window.
7. Verify the windows are properly calibrated by operating the express down and up features. Repeat this procedure if the calibration failed. If unable to properly calibrate after the second attempt, check the Driver's Door Module (DDM) and Passenger's Door Module (PDM) for Diagnostic Trouble Codes (DTCs) and correct as required.
