Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and a Phillips screwdriver.
Ensure the vehicle is in park and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Clean Window Switch

Remove the door panel using a socket set and flathead screwdriver.
Disconnect the window switch connector.
Clean the switch terminals with electrical contact cleaner.
Reconnect the switch and test its functionality.

3. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Pull the fuse and inspect it for continuity; replace if blown.
Reinstall the fuse and retest the window operation.

4. Inspect Wiring and Connections

Visually inspect the wiring harness connected to the window motor for any fraying or damage.
Ensure all connectors are secure and free of corrosion.
Repair any damaged wiring using appropriate automotive wire and connectors.

5. Test and Replace Window Motor

If the switch and fuses are operational, test the voltage at the window motor while operating the switch.
If there is no voltage present, the motor may be defective.
Remove the door panel again to access the window motor.
Disconnect the motor and replace it with a new window motor if necessary.
Reassemble the door panel and retest the window operation.
