Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdriver set, wiring harness tester, and fuses.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Use the vehicle's manual to find the power window fuse location.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity and replace if necessary with a fuse of the same amperage (typically 30A).
Reconnect the battery and test the windows.

3. Inspect and Test Window Switch

Remove the door panel using a screwdriver and panel removal tool.
Disconnect the electrical connector from the window switch.
Use a multimeter to check for continuity when the switch is pressed.
If the switch is faulty, replace it with a new one.

4. Test Window Motor

With the door panel removed, locate the window motor.
Disconnect the motor’s electrical connector.
Use a multimeter to check for voltage at the motor connector when the switch is activated.
If there is voltage but the motor does not work, replace the window motor.

5. Inspect Wiring Harness

Visually inspect the wiring harness for any signs of fraying, corrosion, or disconnection.
Repair any damaged wires using electrical tape or heat shrink tubing.
Ensure all connections are secure.

6. Reassemble Door Panel

Once repairs are completed, reattach the door panel carefully, ensuring all clips are secured.
Reconnect the negative battery terminal and test the power windows again.
