Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, flathead screwdriver, and a torque wrench.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace the Key Fob Battery

Remove the key fob cover using a flathead screwdriver.
Replace the old battery with a new CR2032 battery, ensuring proper polarity.
Reassemble the key fob and test the liftgate functionality.

3. Inspect Wiring and Connections

Remove the interior trim panel of the liftgate using a socket set to access the wiring harness.
Visually inspect the wiring for frays, breaks, or loose connections.
Use a multimeter to check for continuity in the wiring from the switch to the motor.

4. Test the Liftgate Motor

Disconnect the liftgate motor connector.
Using the multimeter, check for voltage at the motor connector when the liftgate button is pressed.
If voltage is present, connect the motor directly to a 12V power source to test its operation.
- If the motor operates, the issue may lie in the wiring or switch; if not, replace the motor.

5. Check the Liftgate Latch Mechanism

Inspect the latch mechanism for any signs of binding or damage.
Clean the latch mechanism if dirty and apply lubricant as necessary.
Ensure that the latch moves freely and is not obstructed.

6. Reassemble and Finalize

Reattach any interior trim panels removed during inspection.
Reconnect the vehicle battery.
Test the liftgate functionality with both the key fob and the interior switch to confirm repair.
