Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, wire stripper/crimper, and screwdrivers.
Disconnect the negative battery terminal to prevent any electrical shorts during the repair.

2. Inspect and Replace Fuse

Locate the fuse box (usually found under the dashboard or in the engine bay).
Remove the cover and identify the power window fuse using the diagram on the cover or the owner's manual.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for a broken filament; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace Power Window Switch

Remove the door panel using a screwdriver and trim tools to access the switch.
Disconnect the switch connector and use a multimeter to check for continuity. If there is no continuity, replace the switch.
Reinstall the new switch by connecting it and securing the door panel back in place.

4. Check and Replace Window Motor

If the switch is operational, locate the power window motor behind the door panel.
Disconnect the motor connector and use a multimeter to check for voltage when the switch is activated.
If there is voltage but the motor does not operate, replace the window motor.
To replace, remove the mounting screws of the motor, detach it from the regulator, and install the new motor in reverse order.
