Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the negative battery terminal to avoid electrical shock.

2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the cover.
Remove the fuse using a fuse puller and inspect it; replace if blown.
Reconnect the battery and test window operation.

3. Inspect and Replace Power Window Switch

Use a trim removal tool to carefully remove the door panel.
Disconnect the power window switch connector.
Test the switch continuity using a multimeter; if faulty, replace with a new switch.
Reassemble the door panel and reconnect the switch.

4. Test Window Motor

Remove the door panel to access the window motor.
Disconnect the motor’s electrical connector.
Use a power source (such as a 12V battery) to apply direct power to the motor terminals.
If the motor operates, reinstall it; if it doesn’t, replace the motor.

5. Inspect Wiring Harness

Check the wiring harness for any signs of damage or corrosion.
Repair any damaged wires using solder and heat shrink tubing.
Ensure all connectors are clean and securely attached.
