Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and a torx bit set.
Disconnect the negative battery terminal to prevent electrical shock.

2. Fuse Inspection

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram on the cover.
Pull the fuse using a fuse puller or pliers and inspect it for continuity. Replace if blown.

3. Power Window Switch Testing

Remove the door panel using a flathead screwdriver to carefully pry it off.
Disconnect the power window switch connector.
Use a multimeter to test for continuity across the switch terminals when pressed. Replace the switch if it fails the test.

4. Wiring Inspection

Visually inspect the wiring harness leading to the power window motor for any signs of damage, fraying, or corrosion.
Repair any damaged wires by soldering or using appropriate connectors.

5. Power Window Motor Testing

If the switch and wiring are functional, locate the power window motor in the door.
Disconnect the motor's electrical connector.
Apply direct battery voltage to the motor terminals (ensure proper polarity) to check if the motor operates. If it does not, replace the motor.
