  1. 1

    Jack the front of the vehicle off the ground and secure with jackstands. Climb underneath and at the rear of the transaxle look for the backup switch. It has a plastic connector with two wires and probably is in a wire loom. It is near the top of the transaxle housing.

  2. 2

    Clean the connector and switch with some solvent. Wipe clean with your rag. Release the connector and inspect for corrosion or loose wires. Repair and clean if necessary.

  3. 3

    Remove the backup switch from the transaxle housing using the correct wrench. Reinstall the new switch and replace the wiring connector. Check for proper operation.

Tips and warnings

  • Corroded and dirty connectors may be the overall problem. Check the connector integrity before replacing the switch.
  • Using a mirror can help in getting an overview of the switch and connector end.
  • Solvents are flammable. Do not use around sparks or flame. Wear goggles when using solvents.
  • Take care to place the jackstands on solid portions of the frame so they don't slip.
  • Undersides of cars collect a lot of dirt. Wear the goggles to protect your eyes from falling debris.
