The window lifters can be controlled from the driver's seat using the main switch, or by manipulating individual door switches. Each window is equipped with a separate reversible drive electric motor. By switching the switch key, the polarity of the motor connection changes 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 circuit breaker, preventing the possibility of the entire system being disabled if a single glass gets jammed.
The electric window lifter operates only when the ignition is on. Additionally, many models have the ability to lock the rear (and sometimes front passenger) door windows from the main switch. Do not forget about this function when checking for windshield wiper failures.
The procedures described are of a very general nature, so if their implementation does not allow you to clearly identify the cause of the failure, take the car to a service station for more detailed diagnostics.
If the window lifts fail, always check the fuse and circuit breaker first.
If the rear door windows are controlled only by the main switch, check the continuity of the interlock switch in the released state. Replace the faulty switch.
Check the condition of the wiring in the circuit section between the switches and the fuse box. Make any necessary repairs.
If the main switch of only one of the windows fails to operate, check the proper operation of this window lifter from an individual switch.
Note: The last does not apply to the driver's window regulator. If the same window regulator operates properly from its own switch, check the continuity of the switch.
If the switch is OK, check for opens and shorts in the circuit between the suspect switch and the power window motor for that particular window.
If the window regulator does not operate with both switches, remove the interior trim panel from the door in question and check for proper power supply to both the switch itself and the regulator drive motor (with the switch in the appropriate position).
With the power supply to the electric motor working properly, separate the glass from the window regulator (see Chapter Body) and move it up and down, checking for freedom of 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 the components is disrupted, eliminate the detected interference, lubricate the rubbing units and replace the damaged parts.
If there is no power to the motor, check the wiring between the switches and the motors for continuity (refer to the wiring diagrams at the end of this Chapter if necessary). If the circuit is equipped with an actuator relay, check the power supply and grounding of the latter.
After making the necessary corrections, re-test the operation of the window lifts.
