Solution

1. Preparation

Tools Required: Socket set, multimeter, flat-head screwdriver, Phillips screwdriver, replacement fuse, lubricant.
Safety Warnings: Disconnect the vehicle battery before starting work to avoid electrical shorts.

2. Inspect and Replace the Fuse

Locate the fuse box and remove the cover.
Identify the fuse for the liftgate and remove it using a fuse puller or pliers.
Inspect the fuse for damage; if blown, replace it with a new fuse of the same amperage.
Reinstall the fuse cover and reconnect the battery.

3. Test the Key Fob

Use a multimeter to check the battery voltage of the key fob.
If the voltage is low, replace the key fob battery with a new one.
Re-test the liftgate operation with the new battery.

4. Inspect Wiring and Connections

Remove the interior panel covering the liftgate area using a flat-head screwdriver or Phillips screwdriver.
Visually inspect the wiring harness for any signs of wear, fraying, or disconnection.
Reconnect any loose connections and repair any damaged wires with electrical tape or connectors.

5. Test the Liftgate Motor

Disconnect the liftgate motor from the wiring harness.
Using jumper wires, connect the motor directly to the vehicle battery to verify it operates.
If the motor runs, reconnect it; if it does not, replace the liftgate motor.

6. Lubricate the Latch Mechanism

Apply a suitable lubricant to the latch mechanism to ensure smooth operation.
Manually operate the liftgate several times to distribute the lubricant evenly.
