Solution
1. Preparation
  • Gather tools: screwdriver set, multimeter, OBD-II scanner, wire connectors, and a replacement fuse if needed.
  • Ensure the vehicle is in a safe working environment, with the ignition off and keys removed.
2. Check and Replace Fuse
  • Locate the fuse box: Find the power window fuse in the driver's side fuse box (Refer to the owner's manual for the exact location).
  • Inspect the fuse: Remove the fuse and check if the filament is broken.
  • Replace the fuse: If blown, replace it with a fuse of the same amperage (usually 15A) and test the windows again.
3. Test Power Window Switches
  • Remove the door panel: Use a screwdriver to remove screws and clips holding the door panel in place.
  • Access the switch harness: Disconnect the power window switch from the wiring harness.
  • Check for continuity: Use a multimeter to test each pin on the switch. If no continuity is found, replace the switch.
4. Inspect Wiring and Connections
  • Examine the wiring: Look for any frayed or damaged wires along the door's wiring harness.
  • Repair or replace damaged wiring: Use wire connectors to fix any damaged sections of wiring.
5. Test Window Motor and Regulator
  • Direct power test: Disconnect the window motor connector and apply 12V power directly from a battery to check if the motor operates.
  • Replace the motor if necessary: If the motor does not operate, replace it with a new one.
6. Reassemble Door Panel
  • Reattach the door panel: Once all repairs and tests are complete, reattach the door panel using screws and clips.
  • Test window operation: Connect the battery and test the power windows to ensure proper operation.
