Solution

1. Preparation

Tools Required: Multimeter, socket set, screwdriver set, OBD-II scanner
Disconnect the vehicle battery before beginning any electrical work.

2. Inspect the Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Remove the fuse for the power windows using a fuse puller or pliers.
Check the fuse for continuity with a multimeter. Replace if blown with a fuse of the same amperage.

3. Test the Window Switch

Remove the door panel using a screwdriver to access the window switch.
Disconnect the switch connector and use a multimeter to test for voltage when the switch is pressed.
If the switch is not receiving power, further investigation into the wiring may be needed.

4. Verify Window Motor Function

With the door panel still removed, locate the window motor.
Disconnect the motor connector and apply direct battery power to the motor terminals.
If the motor operates with direct power, the issue may be with the switch or wiring. If it doesn’t, replace the motor.

5. Inspect Wiring and Connections

Visually inspect the wiring harness for frays, cuts, or corrosion.
Check all connectors for secure fit and any signs of damage.
Repair or replace any damaged wiring as necessary.

6. Reassemble and Test

Reconnect all components and reassemble the door panel.
Reconnect the vehicle battery.
Test the window operation to ensure functionality.
