Solution
1. Preparation
  • Gather tools and parts: OBD-II scanner, multimeter, socket set, screwdrivers, and a replacement window motor or regulator if needed.
  • Disconnect the vehicle battery to ensure safety while working on electrical components.
2. Check and Replace Fuses
  • Locate the fuse box: Refer to the owner’s manual for the exact location.
  • Remove the cover and identify the fuse for the power windows.
  • Use a fuse puller or pliers to remove the fuse and inspect it for continuity.
    • If blown, replace it with a fuse of the same amperage.
    • Reconnect the battery and test the windows again.
3. Inspect and Test Window Switches
  • Remove the door panel using a socket set and screwdrivers to access the window switch.
  • Disconnect the switch harness and use a multimeter to check for continuity across the terminals when the switch is pressed.
    • If there is no continuity, replace the window switch.
4. Test Window Motor
  • Remove the window motor from the door panel.
  • Connect the motor directly to the vehicle battery using jumper wires to test its operation.
    • If the motor does not operate, replace the motor.
5. Inspect Window Regulator
  • Check the window regulator for any signs of wear, binding, or damage.
  • If damaged, remove the regulator by unscrewing it from the door frame.
  • Install a new window regulator following the manufacturer’s specifications.
