Metzger 916233 Switch – Mirror Adjustment

The Metzger 916233 Switch is a precision‑engineered component designed to provide reliable, effortless adjustment of exterior side mirrors on a wide range of Opel models. This switch replaces the original factory unit and restores full functionality to vehicles that have experienced wear or failure in their mirror control system.

Key Features

• Manual Folding Mechanism: The switch incorporates a robust manual folding feature, allowing drivers to collapse the side mirrors for tight parking spaces or when the vehicle is not in use. This design reduces wind resistance and protects the mirror housings.
• Heated Mirror Compatibility: Built to work seamlessly with heated side mirrors, the switch ensures that electrical connections remain stable even at low temperatures, preventing freezing of the heating element.
• Durable Construction: Made from high‑strength plastic and metal components, the switch resists corrosion, vibration, and thermal cycling typical in automotive environments.
• Electrical Integrity: The internal wiring is shielded to minimize electromagnetic interference, guaranteeing smooth operation of the mirror motors and heating circuits.

Vehicle Compatibility

The switch is specifically engineered for a broad spectrum of Opel vehicles. It matches the original equipment specifications (OE) for the following models:

• Opel Agila – A, B, C variants
• Opel Astra – G CC, G Limousine, G Cabriolet, Hatchback
• Opel Vectra – Zafira, Zafira A (T98), Zafira J96
• Opel Zafira – A, B, C, MPV variants
• Other Opel models with the same mirror control architecture (e.g., 0916233 reference OE)

Because the switch is a direct replacement for the factory unit, it fits without modification to the vehicle’s body or interior trim. The part numbers that correspond to this switch include:

• 916233
• 0916233
• 6240108, 6240486, 6240487, 9100302, 9101479, 9226863 (OE references)

Installation Overview

The installation process is straightforward and can be completed by a skilled technician or an experienced DIY enthusiast. The following steps outline the typical procedure:

1. Disconnect the Vehicle Battery: For safety, remove the negative battery terminal to prevent accidental electrical shorts.
2. Remove the Existing Switch: Unscrew the mounting screws that secure the original switch to the door panel. Carefully detach any wiring harnesses connected to the unit.
3. Prepare the New Switch: Align the new Metzger 916233 switch with the mounting holes and connect the wiring harness, ensuring correct polarity and secure contacts.
4. Secure the Switch: Tighten all screws firmly. Verify that the switch is flush against the door panel to avoid rattling during operation.
5. Reconnect the Battery: Reattach the negative terminal and test the mirror adjustment function. Adjust the mirrors manually using the folding lever to confirm smooth movement.

Performance Benefits

• Consistent Mirror Positioning: The switch delivers precise control over mirror angles, improving driver visibility and safety during lane changes or parking maneuvers.
• Reduced Wear on Mechanical Linkages: By providing a reliable electrical interface, the switch minimizes friction in the mechanical adjustment system, extending its lifespan.
• Enhanced Comfort: The heated mirror capability ensures that mirrors remain clear and functional even in cold climates, eliminating fogging or ice buildup.

Maintenance Tips

• Inspect the wiring harness for signs of corrosion or damage every 12 months. Replace any frayed cables promptly.
• Clean the switch housing with a mild detergent to prevent dust accumulation, which can interfere with electrical contacts.
• Verify that the folding lever remains free from debris; lubricate with a silicone-based spray if necessary.
