Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flat-head screwdriver, and a Phillips screwdriver.
Disconnect the battery to ensure safety while working on the electrical system.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or hood of the vehicle.
Use the fuse diagram on the fuse box cover to find the power window fuse.
Remove the fuse with a fuse puller or pliers and inspect it for damage.
If blown, replace it with a new fuse of the same amperage.

3. Test Power Window Switches

Remove the door panel using the Phillips screwdriver to access the power window switch assembly.
Disconnect the switch connector.
Use a multimeter to check for continuity across the switch terminals when pressed. Replace the switch if there is no continuity.

4. Inspect Wiring and Connectors

Check the wiring harness leading to the power window motor for any signs of wear or damage.
Ensure all connectors are securely plugged in and free of corrosion.
Repair or replace any damaged wiring or connectors.

5. Test Power Window Motor

Disconnect the motor from the door panel.
Apply direct battery voltage (12V) to the motor leads to see if it operates.
If the motor does not work, it may need to be replaced.
