Solution

1. Preparation

Gather tools: screwdrivers, socket set, multimeter, OBD-II scanner.
Disconnect the vehicle battery to prevent electrical shorts.
Allow the vehicle to sit for a few minutes to discharge any residual power.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse corresponding to the power windows using the owner's manual.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace with the same amperage if blown.

3. Test and Replace Window Switch

Remove the door panel using a screwdriver and socket set to access the window switch.
Disconnect the window switch connector and use a multimeter to test for continuity.
If the switch is faulty, replace it with a new one.
Reinstall the door panel securely after switch replacement.

4. Inspect and Test Window Motor

If the switch is functional, check the window motor by applying direct battery power to the motor terminals.
If the motor does not operate, it may need to be replaced.
Remove the motor by unscrewing it from its mounting bracket and disconnecting the wiring harness.

5. Reassemble and Test

Reattach the door panel and reconnect the battery.
Test the power windows to ensure they operate correctly.
