2. The power windows can be opened and closed using a master switch controlled by the driver or individual switches located on individual doors. Each window lifter has a separate electric motor that has a reversing function. The position of the control switch determines the polarity and therefore the direction of movement of the glass.
3. The electrical circuit is protected by a fuse and a circuit breaker (breaker). In addition, each electric motor is equipped with an internal electrical circuit breaker; it prevents the entire system from failing when one window regulator gets stuck.
4. The power window system only works when the ignition is on. Also, not many models have a power window lock switch built into the nice switch. This switch, when activated, disables the rear window switches and sometimes the front passenger door switch as well. Be sure to check these items before troubleshooting your power windows.
5. The procedures described are general in nature. If you cannot determine the cause using them, contact your dealer's service department or another service station that has the appropriate equipment.
6. If the power window does not work, be sure to check the fuse and circuit breaker first.
7. If only the power windows of the rear windows do not work, or if the power windows operate only from the main switch, check the rear power window lock switch for the integrity of the electrical circuit in the non-locked position. Replace it if there is no chain integrity.
8. Check the wiring between the switches and the fuse panel for continuity. Repair the wiring if necessary.
9. If only one window's power window does not work from the master switch, check the switch for the other window.
Note: This does not apply to the driver's door window.
10. If the window lifter of any window operates from one switch, but does not operate from the other, check the switch for the integrity of the electrical circuit. Contact your dealer's service department or another service station to check the switch.
11. If the tests show that the switch is OK, check for a short or open in the electrical circuit between the switch in question and the window motor.
12. If either window does not operate with both switches, remove the trim panel from the problem door and check for voltage at the switch and at the motor with the switch activated.

13. If voltage reaches the electric motor, disconnect the glass from the window regulator (see chapter 11). Raise and lower the window manually to check for binding or damage. Also check the window regulator. If the window regulator is not damaged and the window rises and falls smoothly, replace the electric motor. If there is binding or damage, lubricate, repair or replace the components as necessary.
14. If voltage does not reach the motor, check the wiring between the switches and the motors for continuity. You will need to refer to the wiring diagram for the vehicle. If the circuit has a relay, make sure the relay is properly grounded and receiving voltage.
15. Finally, check the operation of the window lifts to ensure that the repair was carried out correctly.
