Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, torx bits, and a trim removal tool.
Disconnect the vehicle battery to prevent any electrical shorts.

2. Remove Door Panel

Use a trim removal tool to carefully pry off the door panel clips.
Remove any screws securing the door panel (typically found near the door handle and the armrest).
Disconnect the electrical connectors for the window switch and any other components attached to the door panel.
Lift the door panel away and set it aside.

3. Inspect and Replace Window Motor

Locate the window motor and regulator assembly inside the door.
Disconnect the wiring harness from the motor.
Remove the bolts securing the motor to the door using a socket set.
Pull the motor out and inspect it for damage.
If necessary, replace the motor with a new one by reversing the removal steps.

4. Check and Replace Window Regulator (if required)

If the window regulator is found to be faulty during inspection, remove it by unbolting it from the door.
Install the new regulator by securing it with bolts and reconnecting the window motor to it.

5. Reassemble Door Panel

Reconnect the electrical connectors for the window switch and any other components.
Position the door panel back onto the door frame and align it with the clips.
Press the panel firmly into place and secure it with screws.
Reinstall any trim pieces removed during disassembly.

6. Final Checks

Reconnect the vehicle battery.
Test the rear sliding window to ensure it operates correctly.
