1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Fuses

Sub-steps:
- Locate the fuse box (usually under the dashboard or in the engine bay).
- Identify the fuse related to the power windows using the diagram on the cover.
- Remove the fuse and inspect it; replace it if blown with a fuse of the same amperage.
Tools Required: Fuse puller or needle-nose pliers.

- Remove the door panel using a trim removal tool.
- Disconnect the window switch connector and test for continuity with a multimeter.
- If faulty, replace the switch with a new one.
- Reassemble the door panel after replacing the switch.
Tools Required: Trim removal tool, multimeter, socket set.

4. Inspect Window Motor and Wiring

Sub-steps:
- If the switches are functional, locate the window motor within the door.
- Disconnect the motor and apply direct power from a battery to test its operation.
- If the motor does not work when powered directly, replace the window motor.
- Check the wiring harness for any signs of damage or corrosion and repair as needed.
Tools Required: Socket set, wire stripper/crimper.

5. Reassemble and Test

Sub-steps:
