Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, screwdrivers.
Disconnect the negative battery terminal to prevent electrical shock.
Gather all necessary tools and parts for the repair.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or near the driver's side.
Identify the correct fuse for the power windows using the fuse diagram on the cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if blown, replace it with a new one of the same amperage (usually 30A).

3. Inspect and Test Window Switches

Remove the door panel using a screwdriver and trim tool to gain access to the window switch assembly.
Disconnect the window switch connector and test for continuity across the switch terminals with a multimeter.
If the switch is faulty, replace it with a new one.

4. Test Window Motor

Connect the multimeter to the window motor connectors.
Activate the window switch while monitoring the voltage; it should read approximately 12 volts.
If the voltage is present and the motor does not operate, replace the window motor.

5. Check Wiring and Connectors

Visually inspect the wiring harness leading to the window motor and switches for any signs of wear, fraying, or corrosion.
Repair or replace any damaged wiring or connectors as necessary.
