Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box, which is usually under the dashboard or in the engine compartment.
Identify the power window fuse (refer to the owner's manual for location).
Remove the fuse using a fuse puller or pliers and inspect it visually.
If blown, replace with a fuse of the same amperage.

3. Inspect and Test Switches

Remove the door panel using a screwdriver to access the window switch assembly.
Disconnect the window switch connector and use a multimeter to test for continuity.
If the switch is defective, replace it with a new one.

4. Check Wiring and Connectors

Visually inspect the wiring harness leading to the window motor for any damage or wear.
Clean any corroded connectors with electrical contact cleaner and reconnect securely.

5. Test the Window Motor

If the window motor is suspected to be faulty, remove it from the door.
Connect the motor directly to a 12V power source (like a car battery) to test its operation.
If the motor does not operate, replace it with a new motor.
