Solution

1. Preparation

Gather all necessary tools and parts. Ensure the vehicle is parked safely.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Tools Required:
- Screwdriver set
- Multimeter
- Trim removal tool
- Socket set

2. Inspect the Power Window Fuse

Locate the fuse box (refer to the owner’s manual).
Remove the power window fuse using a fuse puller.
Inspect the fuse visually; if blown, replace it with a fuse of the same amperage (typically 30A).

3. Test the Power Window Switch

Remove the switch panel by gently prying it up with a trim removal tool.
Disconnect the electrical connector from the switch.
Use a multimeter to check for continuity across the switch terminals when pressed. Replace the switch if it fails the test.

4. Check Power at the Window Motor

With the door panel removed, locate the window motor.
Using a multimeter, check for voltage at the motor connector while pressing the window switch.
If there is no voltage, trace the wiring back to the switch or fuse for faults.

5. Inspect Wiring and Connections

Visually examine the wiring harness for any frays, pinches, or breaks.
Ensure all connectors are securely attached and free from corrosion.
Repair any damaged wiring or connectors as necessary.

6. Test or Replace the Window Motor

If the window motor is not receiving power, confirm its functionality by connecting it directly to a power source (battery).
If the motor is defective, remove it by unscrewing the mounting bolts and disconnecting the wiring harness. Replace it with a new motor and reinstall.
