Solution

1. Preparation

Tools Required:
- Multimeter
- Screwdriver set (Phillips and flathead)
- Torque wrench
- Trim removal tool
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Test the Door Switch

Remove the door panel using a trim removal tool and screwdriver.
Locate the door switch and disconnect the wiring harness.
Use the multimeter to check for continuity when the switch is pressed.
If defective, replace the door switch with a new one.

3. Examine the Door Mechanism

While the panel is removed, inspect the door latch and motor assembly for any visible damage or obstructions.
Manually operate the latch to ensure it moves freely. If it is sticky, clean it with appropriate lubricant.
If the motor is not engaging, test the motor's electrical connection and replace if faulty.

4. Inspect the Wiring Harness

Check the wiring harness for any frayed wires, loose connections, or corrosion.
Repair or replace any damaged sections of the wiring.
Secure all connections and ensure they are firmly in place.

5. Reassemble and Test

Reattach the door panel securely using screws and clips.
Reconnect the negative battery terminal.
Test the sliding doors using both the remote and the interior switch.
