Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shock or short circuits.
Tools required: socket set, multimeter, screwdriver set.

2. Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the cover or in the owner's manual.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse visually for a broken filament.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Inspect and Replace Power Window Switch

Remove the door panel using a screwdriver and trim removal tool.
Disconnect the wiring harness from the power window switch.
Use a multimeter to test the switch for continuity; replace if it fails the test.
Install the new switch by reconnecting the wiring harness and securing the switch in place.

4. Test and Replace Window Motor (if necessary)

If the switch is functional, detach the wiring from the window motor.
Use a multimeter to check for voltage at the motor terminals while pressing the switch.
If there’s power and the motor does not operate, remove the motor by unscrewing it from the window regulator.
Install a new window motor by reversing the removal steps and ensure it is properly secured.

5. Reassemble Door Panel

Reconnect any wiring harnesses that were disconnected.
Align and secure the door panel back onto the door frame.
Reinsert screws and clips to ensure a tight fit.
