Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Make sure to have a clean workspace to prevent damage to the vehicle interior.

2. Check and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box in the cabin (or under the hood) and identify the fuse for the power windows.
Remove the fuse and inspect it for continuity. If blown, replace it with a fuse of the same amperage (typically 30A for power windows).

3. Inspect and Repair Wiring Connections

Tools Required: Screwdriver set, multimeter
Remove the rear door panel carefully using a trim tool to avoid damage.
Inspect all wiring connections to the window motor and switches for loose or damaged wires.
Reconnect any loose wires and repair any damaged wiring with electrical tape or replace as necessary.

4. Test and Replace Window Motor (if necessary)

Reconnect the battery and operate the window switch while checking for voltage at the motor using a multimeter.
If there is power and the window motor does not activate, replace the window motor.
Tools Required: Socket set, ratchet, torque wrench
Remove the window motor by unscrewing it from the regulator and disconnecting the wiring harness.
Install the new window motor and secure it with the appropriate torque (typically around 10-15 Nm).

5. Reassemble Door Panel

Carefully reattach the door panel, ensuring all clips are secure and no wires are pinched.
Test the window operation again before fully securing the panel.
