Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, screwdriver set, panel removal tool.
Disconnect the vehicle's battery to prevent electrical shock or short-circuiting while working on the system.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse related to power windows using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity using a multimeter. Replace if blown.

3. Repair or Replace Wiring

Remove the inner door panel using a panel removal tool and screwdrivers.
Inspect the wiring harness for any visible damage or broken wires at the door hinge area.
Repair any damaged wires by soldering or using appropriate connectors. If extensive damage is found, consider replacing the entire harness.

4. Replace Power Window Switch (if necessary)

If the switch is not receiving power, remove the switch assembly from the door panel.
Test the switch with a multimeter to ensure it functions properly.
If faulty, replace with a new switch and reassemble the door panel.

5. Test Window Motors

If the motors are suspected to be faulty, remove the window motor from the door.
Connect the motor directly to a power source to test its operation. Replace if it does not function.
