Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, Torx screwdriver, wiring harness repair kit (if needed).
Disconnect the vehicle battery to prevent electrical shock.

2. Check and Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if the wire inside is broken, replace with a new fuse of the same amperage.

3. Inspect and Test Switches

Remove the door panel using a flathead screwdriver and Torx screwdriver.
Disconnect the switch assembly from the wiring harness.
Use a multimeter to test for continuity across the switch terminals while pressing the window switch. If no continuity is detected, replace the switch.

4. Inspect Wiring and Harness

Visually inspect the wiring harness for any frays, cuts, or corrosion.
Repair any damaged wiring using the wiring harness repair kit.
Ensure all connections are secure and properly seated.

5. Test Power Window Motor

Disconnect the power window motor from the wiring harness.
Use jumper wires to connect the motor directly to the battery (positive to the positive terminal and negative to the negative terminal).
If the motor operates, it is functional; if not, replace the power window motor.

6. Reassemble and Test

Reconnect all wiring and components.
Reattach the door panel carefully.
Reconnect the vehicle battery.
Test the operation of all power windows.
