Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shock.
Ensure you have a clean workspace to lay out components.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and find the specific fuse for the power windows.
Use a fuse puller to extract the fuse and inspect it for breaks.
If blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Window Switch

Remove the window switch from the door panel.
Use a multimeter to check for continuity when pressing the switch.
If the switch is faulty, replace it with a new one. Ensure it matches the OEM specifications.

4. Inspect and Replace the Window Motor

Remove the door panel using a trim removal tool.
Disconnect the wiring harness from the window motor.
Connect the motor directly to a power source to check functionality.
If the motor does not operate, replace it by unscrewing it from the door and installing a new motor.

5. Check the Window Regulator

While the door panel is removed, inspect the window regulator for any signs of wear or damage.
If the regulator is damaged, remove it by unscrewing it from the door frame and replace it with a new unit.

6. Reassemble the Door Panel

Reattach the door panel, ensuring all clips and screws are secured.
Reconnect the vehicle's battery and test the window operation.
