Solution

1. Preparation

Gather tools: socket set, multimeter, screwdriver set, wiring harness tester.
Disconnect the vehicle battery to prevent electrical shorts.

2. Remove the Door Panel

Use a screwdriver to remove screws securing the door panel.
Gently pry off the door panel using a trim removal tool to detach clips without damaging them.
Disconnect any electrical connectors for the door controls and speakers.

3. Inspect and Test the Window Motor

Locate the window motor at the bottom of the door panel.
Check for any visible damage or disconnections.
Connect the motor directly to the battery using jumper wires to test operation. If the motor does not operate, it may need replacement.

4. Replace the Window Regulator (if necessary)

If the motor is functional but the window still does not operate, the window regulator may need to be replaced.
Remove any fasteners securing the regulator to the door frame.
Carefully detach the regulator from the window glass by unbolting or unclipping it.
Install the new regulator by reversing the removal steps, ensuring it aligns correctly with the window glass.

5. Reassemble the Door

Reconnect all electrical connectors to the door panel.
Align the door panel with the clips and press firmly to secure it.
Reinstall screws to secure the door panel.

6. Reconnect the Battery

Reconnect the vehicle battery once all components are reassembled.
