Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is on a stable surface and the ignition is off.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the fuse for the power windows (check the owner’s manual for the exact location).
Inspect the fuse for continuity using a multimeter; replace if blown.
Reinstall the fuse and reconnect the battery.

3. Check Power Window Switch

Remove the door panel to access the power window switch.
- Use a trim removal tool to gently pry off the panel.
- Unscrew any screws securing the panel.
Disconnect the wiring harness from the switch.
Use a multimeter to test for continuity when the switch is pressed; replace if faulty.

4. Test Window Motor

With the door panel still removed, disconnect the window motor from the wiring harness.
Use jumper wires to connect the motor directly to the battery (positive to positive, negative to negative).
If the motor operates, it is functional; if not, replace the motor.

5. Inspect Wiring Harness

Visually inspect the wiring harness for any frayed wires or corrosion.
Repair or replace any damaged sections of wiring.
Ensure all connectors are secure and free of corrosion.

6. Reassemble Door Panel

Once repairs are confirmed, reconnect the window motor and window switch.
Reattach the door panel, ensuring clips and screws are secured.
Reconnect the negative battery terminal.
