  • Disconnect the vehicle’s battery to ensure safety while working on electrical components.
2. Fuse Inspection
  • Locate the fuse box (typically under the dashboard or in the engine compartment).
  • Remove the cover and find the fuse for the power windows.
  • Replace any blown fuses with ones of the same amperage rating.
3. Switch Replacement
  • Remove the door panel using a socket set and trim removal tools.
  • Disconnect the switch harness from the back of the power window switch.
  • Replace the switch with a new unit, ensuring proper alignment.
  • Reconnect the wiring harness securely.
4. Motor Testing and Replacement
  • Identify the power window motor by removing the door panel completely.
  • Disconnect the motor harness and test the motor by applying 12V power directly.
  • If the motor does not operate, remove it from the door by unscrewing the mounting bolts.
  • Install the new motor in reverse order of removal.
5. Reassembly
  • Reattach the door panel, ensuring all clips and screws are securely fastened.
  • Reconnect the battery and test the power windows for functionality.
