Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, screwdriver set, wire stripper/crimper
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or engine compartment.
Identify the power window fuse (refer to the owner's manual for the exact location).
Remove the fuse and inspect it for continuity; replace it if blown.
Reconnect the battery and test the power windows.

3. Replace Power Window Switch

If the fuse is intact, remove the door panel using a screwdriver to access the power window switch.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter to confirm it is faulty; if so, replace it with a new switch.
Reassemble the door panel and reconnect the battery.

4. Inspect Wiring and Motor

If the switch replacement does not solve the issue, check the wiring harness for frays or disconnections.
If the wiring is intact, access the window motor by removing the door panel and disconnect the motor's wiring.
Use direct power from the battery to test the motor; if the motor does not operate, replace it with a new motor.
Reassemble the door panel after repairs.
