Solution

1. Preparation

Gather necessary tools: socket set, trim removal tool, multimeter.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Remove Door Panel

Use a trim removal tool to carefully pry off the door panel, starting at the bottom and working around the edges.
Remove screws securing the door panel, typically located near the handle and at the bottom.
Gently lift the door panel upwards to disengage the clips and set aside.

3. Inspect Window Motor and Regulator

Locate the window motor and regulator assembly behind the door panel.
Check for any physical damage or obstructions.
Use a multimeter to test the window motor for continuity by connecting the leads to the motor terminals.

4. Replace Components (if necessary)

If the window motor is faulty, disconnect the wiring harness and remove the motor by unscrewing it from the regulator.
Install the new motor by securing it in place and reconnecting the wiring harness.
If the regulator is damaged, remove it by unscrewing it from the door and installing a new one.

5. Reassemble Door Panel

Reattach the door panel by aligning it with the door frame and pressing it down to engage the clips.
Replace all screws removed during disassembly.
Reconnect the battery and test the window operation.
