Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Fuse

Locate the fuse box (refer to the owner’s manual for exact location).
Identify the rear hatch fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.

3. Inspect and Repair Wiring Harness

Reconnect the negative battery terminal temporarily.
Open the rear hatch manually if possible.
Examine the wiring harness for any frayed or damaged wires.
Repair any damaged wires with electrical tape or replace the harness if necessary.

4. Test and Replace Rear Hatch Release Switch

Reconnect the negative battery terminal.
Access the rear hatch release switch (located inside the vehicle or on the remote).
Use a multimeter to test for continuity when the switch is pressed.
If the switch is faulty, disconnect it and replace it with a new switch.

5. Lubricate Latch Mechanism

Manually open the rear hatch if not already open.
Apply a silicone-based lubricant to the latch mechanism and hinges.
Operate the hatch several times to ensure smooth operation.
