Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to avoid electrical shock.
Ensure the work area is clean and organized.

2. Inspect and Replace Fuses

Locate the fuse box, typically under the dashboard or hood.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or needle-nose pliers.
Replace with a new fuse of the same amperage.
Reconnect the battery and test the power windows.

3. Replace the Window Switch

Remove the door panel using a socket set and trim removal tools.
Disconnect the window switch connector from the door harness.
Install the new window switch by connecting the harness and securing it in place.
Reinstall the door panel.

4. Check and Replace the Window Motor (if necessary)

Remove the door panel again if you have already completed this step.
Disconnect the window motor connector.
Test the motor by applying direct power from a battery.
If the motor does not operate, remove the old motor by unscrewing it from the regulator.
