The rearview mirror is an indispensable safety aid, providing the driver with a clear view of traffic conditions behind and alongside the vehicle. The WG1646770001/WG1646770003 mirror features a high-quality glass element with a specialized anti-glare coating that minimizes headlight glare from following vehicles, significantly improving night driving comfort and safety. Its convex design offers a wider field of view, effectively reducing blind spots and aiding in safe lane changes, merging, and reversing operations.
The mirror housing is constructed from high-impact ABS plastic, providing excellent structural integrity and resistance against stone chips, minor impacts, and harsh weather conditions. The internal pivot mechanism allows for smooth, precise adjustment, enabling the driver to quickly and easily set the optimal viewing angle. The WG1646770001/WG1646770003 mirror is a durable, long-lasting replacement that restores full visibility and enhances overall vehicle safety.
The convex mirror design significantly expands the field of view, reducing blind spots and improving situational awareness during lane changes and reversing.
The glass is treated with a reflective coating that reduces glare from headlights, ensuring clear vision and reduced eye strain during night driving.
The ABS plastic housing is tough and durable, protecting the mirror glass from damage caused by stones, debris, and minor collisions.
The set includes both left (WG1646770001) and right (WG1646770003) mirrors, providing a complete replacement solution for both sides of the vehicle.
The engineering of the WG1646770001/WG1646770003 rearview mirror focuses on delivering exceptional optical performance and mechanical durability. The glass is precision-ground to ensure a distortion-free reflection, while the convex curvature is carefully optimized to provide a balanced view that maximizes coverage without compromising depth perception. The mirror head is mounted on a robust ball-joint mechanism that allows smooth adjustment in multiple axes, maintaining its position even during rough road conditions. The housing includes integrated aerodynamic features that reduce wind noise and vibration at highway speeds, contributing to a quieter cabin environment. This mirror is designed to provide years of reliable service, even in the most demanding fleet applications.
Installation is straightforward: remove the old mirror assembly by unbolting it from the door or bracket, transfer any necessary mounting hardware, and install the new mirror using the original fasteners. Ensure any electrical connections (for heated or power-adjustable variants) are properly connected. After installation, adjust the mirror to the desired angle and test the adjustment mechanism. Always check that the mirror is securely fastened before driving. A genuine OEM mirror guarantees correct fitment and optical quality, enhancing safety and driving comfort.

Over time, rearview mirrors can suffer from cracked glass, broken housings, or worn adjustment mechanisms due to impacts, vibration, or environmental exposure. A damaged mirror compromises driver visibility, increasing the risk of accidents. Replacing it with the WG1646770001/WG1646770003 set restores full visibility and safety. It is recommended to inspect mirrors regularly and replace them at the first sign of damage or if the adjustment becomes stiff or loose.
Fleet operators have noted that replacing worn mirrors with the OEM set significantly improves driver confidence and reduces blind-spot-related incidents. The WG1646770001/WG1646770003 mirrors offer superior clarity and durability, making them a cost-effective investment in safety. Regular cleaning and inspection can extend their service life, but replacement is essential when the glass becomes cloudy or the housing is cracked.
Clean the mirror glass regularly using a mild glass cleaner and a soft cloth to remove dirt and residue. Avoid abrasive cleaners that can scratch the reflective coating. Inspect the housing for cracks or looseness and ensure the adjustment mechanism operates smoothly. Check the mounting bolts for tightness and re-torque if necessary. If the mirror is heated, verify the electrical connection and function.
If the mirror becomes loose or the glass becomes cloudy, replace it immediately with the WG1646770001/WG1646770003 set. Always use genuine OEM parts to ensure proper fitment and optical quality. A clear, well-adjusted mirror is essential for safe driving, especially in heavy traffic or adverse weather conditions.
