Problem: Rear Hatch Not Opening in 2020 Toyota Highlander
Tools Required
  • Multimeter
  • Flathead screwdriver
  • Phillips screwdriver
  • Torx screwdriver set
  • Trim removal tool
  • Flashlight
  • Lubricant (such as WD-40)
Repair Instructions

Step 1: Check Key Fob Battery

  1. Open the key fob using a flathead screwdriver.
  2. Replace the battery (usually a CR2032) and reassemble the fob.
  3. Test the rear hatch again with the new battery.

Step 2: Inspect the Interior Button

  1. Remove the panel covering the interior button using a trim removal tool.
  2. Check the button for any signs of damage or loose wiring.
  3. Use a multimeter to check for continuity when the button is pressed. If faulty, replace the switch.

Step 3: Access the Hatch Lock Mechanism

  1. Open the trunk manually (if it is jammed, you may need to pull the emergency release if accessible).
  2. Remove any trim panels covering the hatch lock using a Phillips screwdriver or a Torx screwdriver.
  3. Inspect the latch mechanism for physical damage or misalignment.

Step 4: Electrical Inspection

  1. Disconnect the wiring harness from the hatch lock actuator.
  2. Using a multimeter, check for voltage at the connector when the button is pressed. If there is no voltage, trace back to the fuse box.
  3. Check the fuse for the rear hatch (consult the owner's manual for the exact fuse location).

Step 5: Lubricate the Latch Mechanism

  1. If the latch appears stuck, apply a small amount of lubricant to the moving parts of the latch.
  2. Operate the latch manually to ensure it moves freely.

Step 6: Reassemble and Test

  1. Reconnect any electrical connectors and reattach the trim panels.
  2. Test the hatch operation using both the key fob and interior button.
  3. Ensure that the hatch opens smoothly without obstruction.
Conclusion

If the rear hatch is still not functioning after these steps, it may be necessary to consult a professional technician or visit a dealership for further diagnosis and potential replacement of the hatch actuator or control module.
