Locate the fuse box (typically under the dashboard or hood).
Identify the fuse related to the power windows (refer to the fuse diagram).
Remove the fuse and inspect it; replace if blown with a fuse of the same amperage.

4. Test the Window Switches

Use a multimeter to check for continuity across the window switch terminals.
If no continuity is detected, replace the window switch.

5. Inspect Wiring and Components

Remove the door panel using a door panel removal tool.
Visually inspect the wiring harness for damage or loose connections.
Check the window motor and regulator for any signs of failure or obstruction.

6. Replace Window Motor/Regulator (if necessary)

If the motor is faulty, disconnect the wiring harness and remove the motor using the socket set.
Install the new window motor or regulator by securing it in place and reconnecting the wiring harness.
Reassemble the door panel in reverse order.
