Solution

1. Preparation

Gather necessary tools and parts. Disconnect the vehicle battery to ensure safety.
Tools Required: Socket set, trim removal tool, multimeter, basic hand tools.

2. Remove Door Panel

Use a trim removal tool to carefully pry off the door panel, starting from the bottom and working up.
Remove screws that secure the panel, typically found around the handle and along the edges.
Gently lift the panel off and disconnect any wiring harnesses.

3. Inspect and Test Components

Locate the window motor and regulator assembly.
Use a multimeter to check for voltage at the motor connector when the switch is operated. If there is no power, trace the wiring back to the control module.
If power is present but the motor is unresponsive, proceed to replace the motor.

4. Replace Window Regulator and/or Motor

If the motor is faulty, disconnect the old motor from the regulator.
Remove the regulator from the door by unscrewing its mounting points.
Install the new regulator and motor assembly, securing it with the screws.
Reconnect the motor's electrical connector.

5. Reassemble Door Panel

Reconnect any wiring harnesses to the door panel.
Align the door panel back onto the door frame and press down to secure it.
Replace screws and test the window operation before fully securing the panel.
