The power windows can be controlled from the driver's seat using the master switch, or by manipulating the individual door switches. Each of the glasses is equipped with an individual drive electric motor of a reversible type. Switching the switch key changes the polarity of the motor connection and, as a result, the direction of its rotation.
The circuit is protected by a fuse and a circuit breaker. Each of the electric motors is additionally equipped with an individual interrupter, which prevents the entire system from being damaged if an individual glass is jammed.
The power windows operate only when the ignition is on. Additionally, on many models it is possible to lock the rear windows (and sometimes the front passenger) doors from the main switch. Keep this feature in mind when checking for wiper failures.
The described procedures are of the most general nature, so if their implementation does not allow you to unambiguously identify the cause of the failure, drive the car to a service station for more detailed diagnostics.
- In the event of power window failure, always check the condition of the fuse and circuit breaker first.
- If the rear door windows are operated only from the main switch, check the continuity of the interlock switch in the released state. Replace defective switch.
- Check the condition of the wiring in the section of the circuit between the switches and the fuse box. Make the necessary repairs.
- If only one of the windows from the main switch fails to function, check the operation of this window lifter from the other switch.
Note. The latter does not apply to the driver's door power window.
- If the same power window operates properly from another switch, check the switch for continuity.
- If the switch is OK, test for an open or short in the circuit between the suspect switch and the power window drive motor for that window.
- If the power window does not operate on both switches, remove the trim panel from that door and check for voltage at both the switch and the drive motor (with appropriate switch position) (see accompanying illustration).

- To assess the condition of the switch, check it according to the instructions given.
- With proper power supply to the electric motor, separate the glass from the window regulator (see chapter Body). Move the glass up and down, checking the freedom of its movement. Also check the condition of the regulator. If the regulator is normal, and the glass moves freely in both directions, replace the drive motor. If the smooth movement of components is disturbed, eliminate the detected interference, lubricate the rubbing nodes and replace the damaged parts.
Note. The drive electric motor is built into the power window regulator assembly, a description of the removal procedure of which is given in Chapter Body.
- If power is not supplied to the motor, check for continuity in the wiring in the section of the circuit between the switches and motors (if necessary, refer to the wiring diagrams at the end of this Chapter). If the circuit is equipped with an executive relay, check the power supply and grounding of the latter.
- After making the necessary corrections, recheck the operation of the power windows.
