Solution

Solution

1. Preparation

  • Gather tools: multimeter, socket set, screwdrivers, and wire connectors.
  • Ensure the vehicle is parked on a level surface and the ignition is off.

2. Check and Replace the Fuse

  • Locate the fuse box, typically found under the dashboard or in the engine compartment.
  • Remove the cover and identify the power window fuse (refer to the diagram on the fuse box cover).
  • Use a fuse puller or pliers to remove the fuse and inspect it for continuity.
    • If blown, replace it with a fuse of the same amperage.
    • Recheck the operation of the power windows.

3. Inspect and Test Window Switches

  • Remove the switch panel using a screwdriver to access the power window switches.
  • Disconnect the switch connector and use a multimeter to test for continuity across the switch terminals when pressed.
    • If no continuity is detected, replace the window switch.

4. Check Wiring and Connectors

  • Inspect the wiring harness near the door hinge for any signs of wear, fraying, or disconnection.
  • Repair or replace any damaged wiring and ensure all connectors are secure.

5. Test the Power Window Motor

  • Remove the door panel using a socket set and screwdriver to access the power window motor.
  • Disconnect the motor connector and apply 12V directly from a battery.
    • If the motor operates, it may require reinstallation. If not, replace the motor.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
  • Check for any error codes or warning lights
