Solution

1. Preparation

Gather tools and necessary parts.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace the Fuse

Locate the fuse box under the dashboard and/or engine compartment.
Remove the cover and identify the power window fuse using the diagram.
Pull the fuse using a fuse puller or pliers.
Inspect the fuse for a break in the filament. Replace with a new fuse of the same amperage if blown.

3. Test and Replace the Power Window Switch

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

4. Inspect and Test the Window Motor

If the switch is functional, proceed to test the window motor.
Remove the door panel to access the window motor.
Disconnect the motor connector and use jumper wires to connect the motor directly to a battery (positive to positive, negative to negative).
If the motor does not run, replace it with a new motor.

5. Reassemble and Final Check

Reconnect all components and reattach the door panel.
Restore power by reconnecting the battery.
Test all power windows for proper operation.
