Fixing a Malfunctioning Trunk Latch in a 2022 Toyota Highlander

Tools Required
  • Flathead screwdriver
  • Phillips screwdriver
  • 10mm socket and ratchet
  • Multimeter (for electrical testing)
  • Trim removal tool (optional)
  • Lubricant (WD-40 or similar)
Repair Instructions
Step 1: Battery and Fob Check
  1. Replace Key Fob Battery:
    • Open the key fob using a flathead screwdriver.
    • Remove the old battery and replace it with a new one (usually a CR2032).
    • Reassemble the key fob and test the trunk release.
Step 2: Inspect the Trunk Release Button
  1. Test the Interior Button:
    • Press the trunk release button inside the vehicle.
    • Listen for any clicking sound from the latch area. If there’s no sound, proceed to check wiring.
Step 3: Visual Inspection
  1. Examine the Latch Mechanism:
    • Open the trunk manually and check for any debris or blockages in the latch assembly.
    • Inspect the latch for any visible damage.
Step 4: Wiring Inspection
  1. Check Wiring Harness:
    • Locate the wiring harness connected to the trunk latch mechanism.
    • Look for any frayed or broken wires. Repair or replace as needed.
Step 5: Fuse Check
  1. Locate the Fuse Box:
    • Open the driver’s side door and locate the fuse box cover on the side of the dashboard.
    • Refer to the owner’s manual for the specific fuse related to the trunk release.
  2. Inspect the Fuse:
    • Remove the fuse using fuse pullers or pliers.
    • Check if the metal strip inside the fuse is broken. Replace with a new fuse of the same amperage if necessary.
Step 6: Test the Latch Mechanism
  1. Manually Operate the Latch:
    • Use a flathead screwdriver to press the latch mechanism and see if it opens smoothly.
    • If it sticks, apply a lubricant to the mechanism and work it back and forth to free it up.
Step 7: Reassemble and Test
  1. Reassemble Any Removed Panels:
    • If you had to remove any interior panels to access the latch or wiring, reattach them securely.
  2. Test Functionality:
    • Test the trunk release from the key fob and the interior button multiple times to ensure it operates smoothly.
Step 8: Replace the Latch (if necessary)
  1. Remove the Old Latch:
    • Use a 10mm socket to remove the bolts securing the latch to the trunk.
    • Disconnect any wiring harnesses attached to the latch.
  2. Install New Latch:
    • Position the new latch in place and secure it with bolts.
    • Reconnect any wiring harnesses.
  3. Test the New Latch:
    • Repeat the trunk release tests to confirm proper operation.
Conclusion

By following these steps, you should be able to diagnose and repair a malfunctioning trunk latch on your 2022 Toyota Highlander. If problems persist after following these instructions, consider consulting with a professional technician for further assistance.
