Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and a test light.
Disconnect the negative battery terminal to ensure safety during the repair.

2. Fuse Inspection

Locate the fuse box, typically found under the dashboard and/or in the engine compartment.
Remove the cover and identify the power window fuse (refer to the owner’s manual for specific fuse location).
Inspect the fuse for continuity; replace it if blown with a fuse of the same amperage.

3. Switch Testing

Remove the door panel using a screwdriver to access the window switch.
Disconnect the electrical connector from the switch.
Using a multimeter, check for continuity across the terminals while pressing the switch.
Replace the switch if no continuity is detected.

4. Wiring Inspection

Visually inspect the wiring harness running from the door to the vehicle body for any signs of wear or damage.
If any damaged wires are found, repair them with solder and heat shrink tubing or replace the entire harness if necessary.

5. Motor Testing

Remove the door panel to access the window motor.
Disconnect the motor's electrical connector.
Apply direct power from a battery to the motor terminals to check for operation.
If the motor does not operate, replace it with a new power window motor.
