Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure the vehicle is parked on a flat surface, and the ignition is turned off.

2. Inspect Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and locate the power window fuse using the diagram.
Inspect the fuse for continuity and replace it if blown (use the proper amperage as specified in the owner's manual).

3. Test the Window Switch

Remove the switch panel using a screwdriver.
Disconnect the electrical connector from the switch.
Use a multimeter to check for voltage at the connector while pressing the switch; if no voltage is present, replace the switch.

4. Test the Window Motor

Locate the window motor within the door panel.
Disconnect the motor's electrical connector.
Use jumper wires to apply direct battery voltage to the motor to determine if it operates.
If the motor does not function, replace it.

5. Inspect Wiring Harness

Carefully peel back the door panel to expose the wiring harness.
Look for any frayed wires or loose connections.
Repair or replace any damaged wiring as necessary.

6. Reassemble Components

Reconnect the window switch and motor once repairs are completed.
Reattach the door panel securely, ensuring all clips and screws are in place.
