Door Glass & Regulator
Diagnosis & Testing
- Perform a diagnostic vehicle check to check for the presence of any diagnostic trouble codes.
- Visually inspect the connection at the power window switch. Correctly attach the electrical connector if necessary.
- Disconnect the power window switch, turn the ignition ON with the engine OFF and check the voltage at terminal 13 of the window switch. It should be 11-14 volts. If not, check fuses F18 and EF1 and replace if necessary.
- If fuses F18 and EF1 check out, remove the power window relay and check the voltage at terminal 30 & 85 of the relay socket. (Terminals of the relay socket can be identified by the markings on the relay itself.) Voltage should be 11-14 volts. Repair the open circuit between the fuses and relay if necessary. Using an ohmmeter, check the resistance between ground and terminal 85 of the relay socket. Resistance should be 0 ohms. Repair the open circuit between ground and terminal 85 if necessary.
- Replace the power window relay with a known good relay attempt to operate the windows.
- With the power window switch disconnected, use an ohmmeter to check the resistance between the ground and terminal 8 of the switch. Resistance should be 0 ohms. Repair the open circuit between ground and terminal 8 if necessary.
If the power windows are still not functioning:
- Remove the trim panel from the front door which has an inoperative power window.
- Move a vehicle battery close enough to the door so that the window motor can be powered directly from the battery with jumper wires.
Disconnect the 2-pin window motor connector in the door.
WARNINGTo prevent the fuse in the jumper wire from blowing, do not touch the jumper wires together.
- Attach a jumper wire between the battery negative terminal and one of the terminals in the 2-pin window motor connector.
- Attach a fused jumper wire between the battery positive terminal and the remaining terminal in the 2-pin window motor connector. Unless the motor is at the end of its travel, the window should move with the jumpers attached.
- To move the window in the opposite direction, reverse the jumper wire connections at the window motor connector.
- If the power window does not operate in both directions, the motor must be replaced.
- Before reconnecting the 2-pin window motor connector, connect an ohmmeter between the terminals to check the resistance of the motor and record the ohmmeter reading. Reconnect the motor connector and reinstall the door trim panel and disconnect the electrical connector from the power window switch. At the power window main switch connector, use an ohmmeter to check the resistance between the terminals which lead to the motor that was tested. If the resistance at the main switch does not approximately equal the resistance that was previously measured at the motor connecter, repair the open circuit between the motor and switch. If it does, replace the window switch.
Window Motor & Regulator
- Disconnect the negative battery cable.
Remove the door glass as follows:
- Remove the door trim panel.
- Remove the door seal trim.
- Remove the outside channel molding.
- Remove the screws that secure the glass to the window regulator.
- Remove the bolts and the guide rail.
- Remove the glass from the door.
- Remove the mounting nuts and the regulator.
- Disconnect the electrical connector.
- Connect the electrical connector.
- Install the window regulator and tighten the nuts to 62 inch lbs. (7 Nm).
Install the door glass as follows:
- Install the glass in the door. Install the guide rail and tighten the bolts to 62 inch lbs. (7 Nm).
- Install the glass to the window regulator and tighten the screws to 62 inch lbs. (7 Nm).
- Install the outside channel molding.
- Install the door seal trim.
- Install the door trim panel.
Connect the negative battery cable.
NOTEIf the vehicle is equipped with a one-touch up function, and the driver-s side regulator as been replaced, the motor initialization process must be performed.
Reinitialize the driver-s side window motor as follows:
- Press the driver side window switch until the window is at least 4.0 inches (10 cm) from the top of the window frame.
Pull the driver side window switch to the first step of the UP position and hold until the window is fully UP.
WARNINGDo not put the window switch to the second step of the UP position.
- Continue holding the window switch for approximately 3 seconds after the window motor stall. The driver side window motor assembly is now programmed for the safety function.
- Confirm the reprogramming procedure by performing the auto-up operation.
