Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect the Fuse

Locate the fuse box, typically found in the glove compartment or under the dashboard.
Identify the power window fuse using the fuse diagram.
Remove the fuse and check for continuity using a multimeter. Replace if blown.

3. Test the Power Window Switch

Remove the switch panel using a trim removal tool.
Disconnect the switch connector.
Use a multimeter to test for continuity when pressing the switch. Replace if defective.

4. Test the Window Motor

Access the window motor by removing the door panel (use a socket set and trim tools).
Disconnect the motor from the window regulator.
Connect the motor directly to a 12V battery to see if it operates. If it does not work, replace the motor.

5. Inspect Wiring and Connections

Visually inspect the wiring harness leading to the window motor and switch for any visible damage.
Use a multimeter to check for voltage at the motor connector when the switch is activated. Repair any damaged wires or connections.

6. Reassemble Components

Reattach the window motor and ensure it is securely mounted.
Reconnect the switch panel and door panel, ensuring all clips and screws are properly secured.
Reconnect the negative battery terminal.
