4. Installation Guide

4.1 Important Notes Before Installation

• Professional installation is highly recommended due to the complexity of removing and reattaching interior trim components.
• The entire armrest assembly must be removed from the door panel to install this handle.
• The new handle may require plastic welding or similar methods to securely attach to the existing armrest structure, as it replaces the original integrated handle. The included screws are typically for reattaching the armrest assembly to the door.
• Exercise caution to avoid damaging interior trim or wiring during removal and installation.

4.2 Step-by-Step Installation

1. Preparation: Gather necessary tools, which may include trim removal tools, screwdrivers, and potentially a plastic welding tool.
2. Remove Door Panel: Carefully remove the interior door panel to access the armrest assembly. Refer to your vehicle's service manual for specific instructions on door panel removal.
3. Remove Old Armrest Handle: Once the door panel is off, detach the existing armrest handle from the assembly. This often involves releasing clips or cutting away melted plastic points.
4. Assemble New Handle: The new handle typically comes in multiple pieces. Align and snap the pieces together as shown in the assembly diagrams and video.

5. Secure New Handle: Attach the assembled new handle to the armrest assembly. This step may require plastic welding or using strong adhesive to ensure a secure and permanent bond, as the original handles are often molded in place.
6. Reinstall Armrest Assembly: Once the new handle is securely attached, reattach the armrest assembly to the door panel using the provided screws or original hardware.
7. Reinstall Door Panel: Carefully reattach the door panel to the vehicle door, ensuring all clips and fasteners are properly engaged. Test all functions (window switches, door lock) before fully securing.

5. Operation

The NCOUUOCN Driver Side Door Handle functions identically to the original equipment. Simply pull the handle to open the door from the interior. Ensure the handle moves freely and returns to its resting position after use.

6. Maintenance and Care

To maintain the appearance and longevity of your new door handle trim cover:

• Cleaning: Wipe the surface with a soft, damp cloth. For stubborn dirt, use a mild automotive interior cleaner. Avoid abrasive cleaners or solvents that could damage the finish.
• Avoid Harsh Chemicals: Do not use harsh chemicals, strong detergents, or petroleum-based products, as these can degrade the ABS+PC material.
• Regular Inspection: Periodically check the handle for any signs of looseness or wear.

7. Troubleshooting

If you encounter any issues with your new door handle, consider the following:

• Handle Feels Loose: This often indicates that the handle was not securely attached to the armrest assembly during installation. Re-evaluate the attachment points and consider using plastic welding or a stronger adhesive if necessary.
• Difficulty Opening Door: Ensure that the internal door mechanism is properly connected to the handle. If the mechanism is damaged, replacing the handle alone will not resolve the issue.
• Window Switches Not Functioning: Verify that the window switch panel is correctly seated and all electrical connectors are securely plugged in.

If problems persist after troubleshooting, it is recommended to consult a qualified automotive technician.
