Solution

1. Preparation

Gather required tools and parts.
Disconnect the vehicle's battery to ensure safety.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram.
Inspect the fuse; if blown, replace it with one of the same amperage.
Reinstall the fuse box cover.

3. Test and Replace Window Switch

Remove the door panel using a trim removal tool.
Disconnect the electrical connector from the window switch.
Using a multimeter, test the switch for continuity.
If defective, replace with a new switch and reconnect the wiring.

4. Test and Replace Window Motor

With the door panel removed, disconnect the window motor's electrical connector.
Apply a 12V power source directly to the motor terminals to test functionality.
If the motor does not operate, remove it from the regulator by unscrewing it.
Install a new window motor and reconnect the electrical connector.

5. Inspect Window Regulator

If the window motor is functional, inspect the window regulator mechanism.
Check for any physical obstructions or damage.
If the regulator is faulty, remove the window from the regulator, unscrew the regulator, and replace it.

6. Reassemble Door Panel

Reattach the window to the regulator if it was removed.
Reconnect all wiring and carefully reinstall the door panel.
Ensure all clips and screws are securely fastened.
