Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdriver set, wire strippers, and electrical tape.
Ensure the vehicle is parked on a level surface with the ignition off for safety.

2. Check and Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Use a fuse puller or pliers to remove the power window fuse.
Inspect the fuse for continuity. If blown, replace with an identical fuse (check owner's manual for specification).
Reinsert the fuse and check if the window operates.

3. Inspect and Test the Switch

Remove the door panel using appropriate screwdrivers to access the power window switch.
Unplug the switch connector and use a multimeter to test for continuity.
- Set the multimeter to the continuity setting.
- Press the switch while probing the terminals. A beep indicates functionality.
If the switch is faulty, replace it with a new one.

4. Test the Window Motor

After confirming the switch is functional, access the window motor.
Disconnect the motor connector and use a jumper wire to connect the motor directly to the battery (positive to positive, negative to negative).
If the motor operates, it is functional; if not, replace the window motor.

5. Inspect Wiring and Regulator

If the window motor is working, inspect the wiring harness for frays or loose connections.
Check the window regulator for any mechanical obstructions and ensure it is properly mounted.
Lubricate the regulator if there are signs of difficulty in movement.
