Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the workspace is clear and safe.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse for the power windows using a fuse puller.
Inspect the fuse for continuity; replace it if it is blown with a new fuse of the same amperage.

3. Inspect Window Switches

Remove the door panel using a socket set and trim removal tools to access the window switches.
Disconnect the switch connector and use a multimeter to test for continuity when the switch is pressed.
Replace the switch if it fails the continuity test.

4. Test and Replace Window Motor

Access the window motor by removing any necessary panels.
Disconnect the motor from the harness.
Use jumper wires to connect the motor directly to the battery to check for functionality.
If the motor does not operate, replace it with a new motor.

5. Reassemble and Test

Reconnect all components, ensuring all connectors are secure.
Reattach the door panel and ensure all clips and screws are fastened.
Reconnect the vehicle battery and test the power windows.
