Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and screwdriver.
Disconnect the vehicle battery to ensure safety while working on electrical systems.

2. Fuse Inspection

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Remove the fuse for the power windows (refer to the owner’s manual for the exact location).
Inspect the fuse visually or test it with a multimeter; replace if blown with the same amperage rating.

3. Switch and Wiring Check

Remove the door panel using a screwdriver to access the window switch.
Disconnect the switch connector and test continuity with a multimeter.
If the switch is faulty, replace it with a new one.
Inspect the wiring harness for any damage or loose connections.

4. Window Motor Testing

With the door panel removed, locate the window motor.
Disconnect the motor connector and test for voltage with a multimeter while activating the switch.
If voltage is present but the motor does not respond, replace the window motor.
If there is no voltage, trace the wiring back to the switch for further inspection.

5. Reassembly

After repairs, reassemble the door panel and ensure all clips and screws are secured.
Reconnect the vehicle battery.
