Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure the vehicle is in a safe, well-lit area and turn off the ignition.
Disconnect the battery to avoid electrical shock.

2. Inspect and Clean Window Switch

Remove the door panel carefully using a trim removal tool.
Detach the window switch assembly.
Clean the contacts of the switch with electrical cleaner.
Reassemble the switch and test for functionality.

3. Check and Replace Window Motor (if necessary)

If the switch test is inconclusive, locate the window motor at the bottom of the door panel.
Disconnect the motor's wiring harness.
Use a multimeter to test for power at the connector when the switch is pressed.
If no power is detected, the wiring may need repair; if power is present, the motor may need replacement.
Remove the motor by unscrewing the mounting bolts and replacing it with a new motor.

4. Reassemble and Reconnect

Reattach all components in reverse order of disassembly.
Ensure all connectors are securely fastened.
Reconnect the battery and test the window functionality.
