2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse for the power windows using a fuse puller.
Inspect the fuse. If blown, replace it with a new fuse of the same amperage (refer to the owner's manual for specifications).
Reconnect the battery.

3. Replace Power Window Switch

Remove the door panel using a socket set and trim removal tool.
Disconnect the power window switch harness.
Replace the faulty switch with a new one. Ensure it matches the original in specifications.
Reconnect the harness and reattach the door panel.

4. Inspect and Replace Window Motor

If the switch replacement does not resolve the issue, locate the window motor.
Disconnect the wiring harness from the window motor.
Remove the window motor from the regulator by unscrewing it (note the orientation).
Install the new window motor, ensuring it is securely fastened.
Reconnect the wiring harness.

5. Test the System

Reconnect the battery and test the power windows for operation.
If windows work, reassemble any remaining panels and ensure everything is securely in place.
