Solution

1. Preparation

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

2. Inspect and Replace Fuse

Locate the fuse box: Refer to the owner's manual to find the exact location of the power window fuses.
Remove the cover: Use a flathead screwdriver to gently pry off the fuse box cover if necessary.
Check fuses: Identify the power window fuse and inspect it for continuity using a multimeter.
- If blown, replace it with one of the same amperage.

3. Testing the Power Window Switch

Remove the switch panel: Use a flathead screwdriver to pry the switch panel out carefully.
Disconnect the switch: Unplug the electrical connector from the switch.
Test the switch: Use a multimeter to check for continuity across the switch terminals when operated.
- If faulty, replace the switch with a new one.

4. Testing the Window Motor

Access the window motor: Remove the door panel by unscrewing any screws and gently prying it away.
Disconnect the motor: Unplug the motor connector from the wiring harness.
Apply direct voltage: Use jumper wires to connect the motor directly to the battery to check for functionality.
- If the motor operates, the issue may lie in the wiring or switch; if not, replace the motor.
