Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Disconnect the negative battery terminal to ensure safety while working.

2. Inspect and Replace Fuse

Locate the fuse box: Refer to the owner’s manual for the exact location.
Remove the fuse: Use a fuse puller or pliers to extract the power window fuse.
Inspect the fuse: If the metal strip inside the fuse is broken, replace it with a new fuse of the same amperage (typically 30A for power windows).
Reinstall the fuse: Ensure it is securely seated in the fuse box.

3. Test and Replace Power Window Switch

Remove the switch panel: Use a flathead screwdriver to gently pry up the switch panel.
Disconnect the switch: Unplug the connector from the power window switch.
Test the switch: Use a multimeter to check for continuity when pressing the switch. Replace if defective.
Reinstall the switch: Plug the connector back and snap the panel into place.

4. Check Window Motors

Access the window motor: Remove the door panel by unscrewing any fasteners and lifting the panel off.
Disconnect the motor: Unplug the electrical connector from the window motor.
Direct power test: Use jumper wires to connect the motor directly to the battery to check for operation. Replace if non-functional.

5. Inspect Wiring and Regulators

Examine wiring: Look for any signs of wear, fraying, or corrosion in the wiring harness.
Inspect window regulators: Check for mechanical failure or obstructions in the track. Replace if damaged.
