Magneti Marelli AC1264 Window Regulator

Magneti Marelli AC1264 Window Regulator

The Magneti Marelli AC1264 is a high‑performance window regulator designed for front right windows of Volkswagen Transporter and related models. It delivers precise, silent operation and reliable durability in demanding automotive environments.

Key Technical Features

• Model Code: AC1264 (also referenced as 350103126400)
• Application: Right front electric window lift for VW Transporter T5 and similar chassis.
• Drive Type: Electric motor‑driven regulator with integrated gear train.
• Material Construction: High‑strength steel housing, reinforced plastic components, and corrosion‑resistant metal fittings.
• Operating Range: Full window travel from fully closed to fully open without stalling or binding.
• Torque Capacity: Designed to handle the weight of standard automotive glass panels while maintaining smooth motion.
• Noise Level: Ultra‑quiet operation, meeting OEM noise specifications for passenger comfort.
• Compatibility: Engineered to fit original vehicle architecture, including mounting brackets and electrical harness connections.

Design & Engineering Excellence

The AC1264 incorporates a precision gear train that translates motor rotation into linear motion. The gear set is engineered with low backlash to prevent rattling and ensure consistent window positioning. A spring‑loaded return mechanism guarantees the window returns smoothly to its closed position when the power supply is cut.

All moving parts are sealed against dust, moisture, and temperature extremes, extending service life in both temperate and harsh climates. The regulator’s housing features a protective coating that resists corrosion from road salts and environmental exposure.

Installation & Integration

Designed for seamless integration into the vehicle’s existing architecture, the AC1264 uses standard mounting brackets and electrical connectors. Technicians can install the regulator by following a straightforward procedure:

1. Remove the existing window assembly.
2. Attach the new regulator to the door frame using supplied bolts.
3. Connect the electrical harness, ensuring correct polarity and secure contacts.
4. Reinstall the glass panel and test operation for smooth lift and lock.

The design allows for quick replacement without requiring extensive modifications to the door or vehicle body.

Performance & Reliability

• Consistent Lift Speed: Maintains a steady velocity across the entire travel range, preventing sudden jerks.
• Low Maintenance: Requires no lubrication after installation; all components are pre‑lubricated and sealed.
• Durability: Meets or exceeds OEM lifespan expectations under normal usage conditions.
• Safety Compliance: Built to meet automotive safety standards for electrical and mechanical performance.

Applications & Vehicle Compatibility

The AC1264 is specifically engineered for the right front window of the VW Transporter T5 platform, but its design principles make it suitable for other vehicles with similar door geometry. Its compact size and robust construction allow it to fit within tight space constraints while delivering reliable performance.

Maintenance Tips

• Inspect electrical connections periodically for corrosion or looseness.
• Check the window seal and glass alignment to ensure smooth operation.
• Replace any damaged mounting hardware promptly to avoid compromising structural integrity.

Conclusion

The Magneti Marelli AC1264 Window Regulator exemplifies engineering precision, durability, and user‑friendly design. Its seamless integration with the VW Transporter T5 platform and superior performance make it an ideal choice for both OEM replacements and high‑quality aftermarket installations.
