Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety before working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if blown with one of the same amperage.

3. Replace Power Window Switch (if faulty)

Remove the door panel using a socket set and trim removal tools.
Disconnect the wiring harness from the power window switch.
Replace the switch with a new one and reconnect the wiring harness.
Reassemble the door panel and secure it with screws.

4. Repair or Replace Window Motor (if necessary)

Access the window motor by removing the door panel.
Disconnect the motor from the wiring harness.
Check if the motor operates by applying direct voltage from a battery.
If it does not work, replace the window motor with a new unit.
Reinstall the motor and reconnect the wiring harness.
