Solution

1. Preparation

Tools Required:
- Screwdrivers (Phillips and flathead)
- Socket set
- Multimeter
- Wiring diagrams (for reference)
Disconnect the negative battery terminal to ensure safety during repairs.

2. Replace the Fuse (if blown)

Locate the fuse box in the vehicle, usually found under the dashboard or in the engine compartment.
Remove the fuse for the power windows using a fuse puller.
Replace it with a new fuse of the same amperage (check the user manual for specifications).
Reconnect the negative battery terminal and test the windows.

3. Replace the Window Switch (if faulty)

Remove the door panel using a screwdriver and trim tools to access the window switch.
Disconnect the electrical connector from the switch.
Test the new switch with a multimeter before installation or connect the new switch directly to the wiring harness.
Reinstall the switch and door panel securely.

4. Replace the Window Motor (if defective)

Remove the door panel and locate the window motor attached to the window regulator.
Disconnect the motor's electrical connector.
Remove the bolts securing the motor to the regulator and detach the motor.
Install the new motor by reversing the removal steps and reconnecting the electrical connector.

5. Repair or Replace Window Regulator (if damaged)

With the door panel removed, assess the window regulator for any broken components.
If damaged, unbolt the regulator from the door and detach it from the window.
Install the new regulator by following the removal steps in reverse, ensuring the window is aligned properly.
