Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and locate the power window fuse using the diagram on the cover.
Remove the suspected blown fuse with a fuse puller or needle-nose pliers.
Replace it with a new fuse of the same amperage rating.
Reconnect the battery and test the power windows.

3. Replace the Power Window Switch

If the fuse is intact, remove the door panel to access the power window switch.
- Use a socket set to remove screws securing the door panel.
- Gently pry off the panel using a trim removal tool to avoid damage.
Disconnect the wiring harness from the power window switch.
Install the new switch by connecting the wiring harness and securing it in place.
Reassemble the door panel.

4. Test the Power Window Motor

If the switch replacement does not resolve the issue, access the power window motor by removing the door panel as described above.
Disconnect the motor from the wiring harness.
Use a multimeter to check for voltage at the motor connector when the switch is activated.
If no voltage is detected, trace the wiring back to the switch for issues.
If voltage is present but the motor does not operate, replace the power window motor.
