1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during the repair process.
Tools Required:
- Socket set
- Screwdrivers (flathead and Phillips)
- Multimeter
- Trim removal tool

2. Remove the Door Panel

Carefully use a trim removal tool to pry off the door panel clips.
Remove screws securing the door panel (usually located near the handle and bottom of the panel).
Gently lift the door panel upwards to detach it from the door frame, ensuring no wires are snagged.

3. Inspect and Replace Window Motor/Regulator

Locate the window motor and regulator assembly behind the door panel.
Disconnect the motor wiring harness.
If the motor is faulty, remove the mounting screws and take out the motor.
If the regulator is damaged, unbolt and remove the entire assembly from the door.
Install the new motor or regulator by reversing the removal steps, ensuring all bolts are tightened to manufacturer specifications (typically around 7-10 Nm).

4. Reconnect Wiring and Test Functionality

Reconnect the wiring harness to the new motor.
Before reassembling the door panel, reconnect the battery and test the window operation to ensure proper functionality.
If the window operates correctly, proceed to reassemble the door panel.

5. Reassemble Door Panel

Align the door panel with the door frame and press down to secure the clips.
Reinsert and tighten all screws removed during disassembly.
Reattach any trim pieces that were removed.
