Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, replacement fuses, and a new key fob battery if needed.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace the Key Fob Battery

Remove the key fob cover using a flathead screwdriver.
Replace the old battery with a new one of the same type (usually CR2032).
Reassemble the key fob and test the liftgate operation.

3. Check and Replace the Liftgate Fuse

Locate the fuse box, typically found under the dashboard on the driver's side.
Identify the power liftgate fuse (refer to the fuse diagram on the cover).
Remove the fuse using a fuse puller and inspect it; if blown, replace it with a fuse of the same amperage (10A or as specified).
Reconnect the battery and test the liftgate.

4. Inspect the Liftgate Motor and Wiring

Remove the interior panel of the liftgate by unscrewing the fasteners and gently prying it off.
Locate the liftgate motor and check the wiring harness for any signs of damage or corrosion.
Use a multimeter to test for voltage at the motor connector when the liftgate switch is pressed.
If the motor shows no power, trace the wiring back to the switch; repair any damaged wires.

5. Check and Replace the Liftgate Switch

With the multimeter, test the liftgate switch for continuity.
If it fails the continuity test, replace the switch by removing the panel surrounding it and disconnecting the wiring harness.
Install the new switch and reassemble the panel.

6. Reassemble and Test

Reattach any interior panels and ensure all screws are tightened.
Reconnect the battery and test the liftgate operation using both the key fob and interior switch.
