3. Operating Instructions

The Dorman 901-152 Tailgate Release Switch operates identically to the original equipment. To open the tailgate, simply press the button on the switch. Ensure the vehicle is unlocked or the appropriate unlock sequence has been performed for the tailgate to release.

4. Maintenance

The tailgate release switch is designed for long-term reliability with minimal maintenance. However, periodic inspection can help ensure continued performance:

• Cleaning: Keep the exterior of the switch clean from dirt, debris, and moisture. Use a soft, damp cloth for cleaning. Avoid harsh chemicals or abrasive cleaners.
• Inspection: Periodically check the switch for any signs of physical damage, corrosion, or loose connections. Ensure the button operates smoothly without sticking.
• Wiring: Inspect the wiring harness connected to the switch for any fraying, cuts, or signs of wear.

5. Troubleshooting

If the tailgate release switch is not functioning correctly, consider the following troubleshooting steps:

• No Response When Pressed:
  • Check if the vehicle's doors are unlocked. Some vehicles require the doors to be unlocked for the tailgate release to function.
  • Verify the electrical connection to the switch is secure and free of corrosion.
  • Inspect the vehicle's fuse box for a blown fuse related to the tailgate or trunk release. Refer to your vehicle's owner's manual for fuse locations.
  • Test for power at the switch connector using a multimeter. If no power is present, the issue may be further up the electrical circuit.
• Intermittent Operation:
  • This could indicate a loose or corroded electrical connection. Disconnect and reconnect the connector, ensuring it is clean and tight.
  • Inspect the wiring for any damage that might cause intermittent contact.
• Switch Feels Stiff or Stuck:
  • Clean around the button area to remove any accumulated dirt or debris.
  • If the switch mechanism itself is physically damaged or worn, replacement may be necessary.

If these steps do not resolve the issue, it is recommended to consult a professional automotive technician.
