Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, Torx screwdriver.
  • Ensure the vehicle is parked on a level surface with the ignition off.
  • Disconnect the negative battery terminal to prevent any electrical shorts.
2. Check and Replace Fuse
  • Locate the fuse box (usually in the glove compartment or under the dashboard).
  • Remove the fuse for the power windows using a fuse puller or pliers.
  • Inspect the fuse visually and with a multimeter for continuity.
  • Replace the fuse if it is blown (use the correct amperage as indicated in the owner's manual).
3. Inspect and Test the Power Window Switch
  • Remove the switch panel using a flathead screwdriver (carefully pry it up).
  • Disconnect the switch connector.
  • Use a multimeter to check for continuity across the switch terminals when pressed.
  • Replace the switch if no continuity is found.
4. Check Wiring and Connections
  • Inspect the wiring harness in the door panel for any frayed wires or loose connections.
  • If damaged, repair the wiring with solder or electrical connectors and wrap with electrical tape.
5. Test the Power Window Motor
  • Remove the inner door panel using a socket set and Torx screwdriver.
  • Disconnect the motor connector.
  • Apply direct power from a 12V source to the motor terminals to check for operation.
  • Replace the motor if it does not activate.
6. Reassemble and Test
  • Reinstall the door panel and ensure all clips and screws are secured.
  • Reconnect the negative battery terminal.
  • Test each power window switch to confirm functionality.
