Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked safely and engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the power windows using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers and inspect it for continuity.
If blown, replace with a new fuse of the same amperage.

3. Test and Replace Window Switches

Use a multimeter to check continuity across the window switch terminals.
If the switch is defective, remove the switch panel by prying it off carefully with a trim removal tool.
Disconnect the old switch and install the new switch by reversing the removal process.

4. Inspect and Replace Window Motor

Remove the door panel carefully using a trim tool to avoid damage.
Disconnect the wiring harness from the window motor.
Test the motor directly with a 12V power source; if it does not operate, proceed with replacement.
Remove the motor by unscrewing it from the window regulator and install the new motor, ensuring it is properly aligned.

5. Reassemble Door Components

Reconnect the wiring harnesses and ensure all connections are secure.
Reinstall the door panel carefully, ensuring all clips and screws are replaced.
Reconnect the vehicle battery.
