Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, fuse puller, wire connectors.
Disconnect the negative terminal of the battery to prevent electric shock.

2. Inspect and Replace Fuse

Locate the fuse box 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 and inspect it:
- If the fuse is blown, replace it with a new fuse of the same amperage (typically 30A).
- Reinstall the fuse and reconnect the battery.

3. Test Power Window Switch

Remove the door panel to access the power window switch.
- Use a screwdriver to remove screws and carefully pry off the panel.
Disconnect the switch connector.
Use a multimeter to check for voltage at the switch connector when pressing the switch.
- If no voltage is present, replace the switch.
- If voltage is present, proceed to test the window motor.

4. Test Window Motor

Disconnect the window motor from its connector.
Use a multimeter to test the motor for continuity.
- If there is no continuity, replace the window motor.
- If continuity exists, apply direct power to the motor using jumper wires from the battery.
- If the motor operates, check the wiring harness for issues; if it does not, replace the motor.

5. Reassemble and Test

Reinstall the door panel, ensuring all clips and fasteners are secured.
Reconnect the battery and test all power windows for functionality.
