Solution

1. Preparation

Gather tools and materials: OBD-II scanner (if needed), multimeter, socket set, flathead screwdriver, and replacement parts (if necessary).
Ensure the vehicle is parked on a flat surface with the ignition turned off.

2. Check and Replace Fuse

Locate the fuse box as indicated in the owner's manual.
Remove the cover and inspect the power window fuse.
If the fuse is blown, replace it with a new fuse of the same amperage (usually 30A for power windows).
Recheck the operation of the windows.

3. Inspect and Replace Window Switch

Remove the switch panel using a flathead screwdriver to gently pry it up.
Disconnect the switch connector and inspect for corrosion or damage.
Test the switch with a multimeter for continuity. If it fails, replace it with a new switch.
Reconnect the switch and replace the panel.

4. Test and Replace Window Motor (if necessary)

Remove the door panel using a socket set to access the window motor.
Disconnect the motor connector and test it with a multimeter to check for voltage when the switch is activated.
If the motor is defective, remove the old motor and install a new one, securing it with bolts to the door frame.
Reconnect the wiring and reassemble the door panel.

5. Inspect Wiring Harness

If the issue persists, thoroughly inspect the wiring harness for damage or disconnection.
Repair any damaged wires with appropriate connectors and electrical tape.
Ensure all connections are secure and free from corrosion.
