Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked safely with the engine off.
Disconnect the battery to prevent electrical shock.

2. Check and Replace Fuse

Locate the fuse box (usually 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 it is blown with a fuse of the same amperage.

3. Inspect Window Switches

Remove the door panel using a trim tool and screwdriver.
Disconnect the window switch connector.
Use a multimeter to test the switch for continuity when pressed.
Replace the switch if it shows no continuity or is damaged.

4. Test Window Motor

Disconnect the window motor connector.
Using jumper wires, connect the motor directly to the battery to test if it operates.
If the motor operates, the issue may lie in the wiring or switch; if not, replace the motor.

5. Check Wiring and Connections

Inspect the wiring harness for any signs of fraying or damage.
Ensure all connectors are secure and free of corrosion.
Repair or replace any damaged wiring or connectors.

6. Inspect Window Regulator

If the motor works, check the window regulator for any mechanical obstructions or damage.
Manually move the window glass to ensure it is not stuck.
Replace the window regulator if it is defective.
