Solution
1. Preparation
  • Gather tools: multimeter, screwdriver set, trim removal tool, and replacement fuse if needed.
  • Ensure the vehicle is turned off and parked safely.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect Fuses
  • Locate the fuse panel: Refer to the owner's manual for the exact location.
  • Remove the fuse for the power windows: Use a fuse puller or needle-nose pliers.
  • Check the condition of the fuse: Replace it if it is blown (check for a broken metal strip inside).
  • Reinstall the fuse: Ensure it is seated properly.
3. Test the Window Switch
  • Remove the switch panel: Use a trim removal tool to pry off the panel gently.
  • Disconnect the electrical connector: Pull the connector straight out.
  • Test for continuity: Set the multimeter to the continuity setting and test the switch terminals while pressing the switch. Replace the switch if there is no continuity.
4. Inspect Wiring Harness
  • Visual inspection: Check the wiring harness both at the door and switch for any visible damage, fraying, or corrosion.
  • Reconnect any loose connections: Ensure all connectors are tightly secured.
  • Repair any damaged wiring: Use electrical tape or solder and heat shrink tubing for repairs.
5. Check Window Lock Feature
  • Locate the window lock switch: It’s typically found on the driver’s side control panel.
  • Toggle the switch: Ensure it is in the "unlocked" position and try operating the windows again.
6. Reconnect Battery
  • Reconnect the negative terminal: Ensure it is securely tightened.
  • Test the windows: Attempt to operate each window using the switches.
