Solution
1. Preparation
  • Gather tools: socket set, multimeter, OBD-II scanner, and a flathead screwdriver.
  • Disconnect the vehicle battery to ensure safety while working on electrical components.
2. Inspect and Replace Fuses
  • Locate the fuse box (usually under the dashboard or in the engine bay).
  • Remove the power window fuse using the fuse puller tool.
  • Inspect the fuse for any signs of damage or a broken filament.
  • Replace with a new fuse of the same amperage if blown.
3. Test Power Window Switch
  • Remove the door panel using a flathead screwdriver to pry off clips gently.
  • Disconnect the switch connector and set the multimeter to continuity mode.
  • Test the switch terminals for continuity when pressed; replace the switch if faulty.
4. Inspect Wiring and Connections
  • Visually inspect the wiring harness connected to the power window motor for frays or breaks.
  • Check all connectors for corrosion or loose connections; clean or repair as necessary.
5. Test the Window Motor
  • If the switch is functional, apply direct battery power to the window motor terminals using jumper wires.
  • If the motor operates, the issue may be with the window regulator or connections; if not, replace the motor.
6. Reassemble and Test
  • Reattach the door panel securely.
  • Reconnect the battery and test the power windows for proper operation.
