Solution

1. Preparation

Gather tools: Multimeter, socket set, screwdrivers, OBD-II scanner, and wire connectors.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Refer to the owner's manual to find the power windows fuse.
Remove the fuse and inspect it; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Master Window Switch

Remove the trim panel around the master window switch using a trim removal tool.
Disconnect the switch connector and verify continuity with a multimeter.
If defective, replace the master switch with a new one.

4. Check and Replace the Power Window Motor
