Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and a test light.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse related to 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 it with a fuse of the same amperage.

3. Test and Replace Power Window Switches

Remove the door panel using a screwdriver and carefully detach any clips.
Disconnect the power window switch connector.
Using a multimeter, check for continuity across the switch terminals when pressed.
If faulty, replace the switch with a new one by reversing the removal steps.

4. Inspect and Replace Window Motors

If the switches are functional, disconnect the window motor from the door.
Connect the motor directly to a power source (battery) to test for operation.
If the motor does not operate, it will need to be replaced. Remove the old motor and install the new one, ensuring proper alignment with the window regulator.

5. Reassemble Door Panel

Once repairs are complete, reattach the door panel by aligning it with the clips and securing with screws.
Test the power windows before fully tightening screws to ensure proper operation.
