Solution
1. Preparation
  • Gather tools: socket set, multimeter, flathead screwdriver, Phillips screwdriver, and a test light.
  • Disconnect the battery to prevent electrical shorts.
2. Check the Fuse
  • Locate the fuse box (usually under the dashboard or in the engine compartment).
  • Remove the cover and identify the power window fuse using the diagram.
  • Inspect the fuse; if it is blown, replace it with a fuse of the same amperage.
3. Inspect the Power Window Switch
  • Remove the door panel using a flathead screwdriver to pry off clips and a Phillips screwdriver to remove screws.
  • Disconnect the switch harness and visually inspect for corrosion or damage.
  • Test the switch with a multimeter for continuity when pressed. Replace if faulty.
4. Test the Power Window Motor
  • Access the motor by removing the door panel (as described above).
  • Disconnect the motor connector.
  • Use a multimeter to check for voltage at the motor connector when the switch is pressed.
  • If voltage is present but the motor does not operate, replace the window motor.
5. Examine Wiring Harness and Window Regulator
  • Inspect the wiring harness for any cuts, frays, or loose connections along the door frame.
  • If the wiring is intact, check the window regulator for any mechanical issues.
  • Manually operate the regulator to see if it’s binding; lubricate if necessary or replace if damaged.
