VAN WEZEL 640266 Window Regulator

VAN WEZEL 640266 Window Regulator

The VAN WEZEL 640266 Window Regulator is a high‑performance electric window lift designed for the front right side of BMW models, particularly the 3 Series (E36/E46) and other compact sedans. It delivers smooth, reliable operation with a robust build that meets OEM specifications.

Key Features

• Electric Drive: Powered by a lightweight electric motor that provides quiet, precise control of the window position.
• Durable Construction: Constructed from high‑strength aluminum alloy and reinforced plastic components to resist corrosion and fatigue over long service life.
• Compact Design: The regulator’s slim profile allows it to fit seamlessly into tight engine bay spaces without compromising other mechanical systems.
• Integrated Wiring Harness: Comes with a pre‑wired harness compatible with standard BMW electrical connectors, simplifying installation.
• Safety Features: Built-in limit switches prevent over‑extension and reverse motion, protecting the glass from damage.

Compatibility Overview

The regulator is engineered for a wide range of BMW 3 Series models. Its part number variations—such as 640266, 0640266, and regional codes like 51331977610—all refer to the same core component, adapted for different markets (Europe, North America, Asia). It is suitable for:

• BMW 3 Series E36 (Compact) – models equipped with M40B16, M43B16, M41D17, and other inline‑four engines.
• BMW 3 Series E46 (Sedan/Compact) – including variants with M52B25, M50B25, M51D25, and S50B30.
• Other compact sedans that use the same window lift architecture.

Installation Highlights

Installing the VAN WEZEL 640266 Window Regulator involves a few critical steps to ensure optimal performance:

1. Removal of Old Regulator: Carefully detach the existing regulator, noting the position of the motor and wiring connections.
2. Alignment Check: Verify that the new unit aligns with the window track and mounting brackets. Misalignment can cause uneven glass movement.
3. Secure Mounting: Fasten the regulator to the vehicle’s body using the supplied bolts, ensuring torque specifications are met.
4. Electrical Connection: Connect the pre‑wired harness to the car’s power supply and control module. The regulator’s built‑in limit switches will automatically calibrate during initial operation.
5. Functional Test: Operate the window from both up and down positions, confirming smooth motion and correct stop points.

Maintenance Tips

To keep the regulator functioning flawlessly, follow these simple maintenance practices:

• Regular Inspection: Check for visible wear on the motor shaft, gear teeth, and track alignment every 10,000 miles.
• Lubrication: Apply a silicone‑based lubricant to the window track once a year to reduce friction.
• Electrical Cleanliness: Inspect wiring connections for corrosion; clean with isopropyl alcohol if necessary.
• Software Updates: If your vehicle’s body control module supports firmware updates, ensure it remains current to maintain compatibility.

Performance Characteristics

The regulator delivers a consistent lift speed of approximately 0.5–0.7 inches per second, depending on battery voltage and load. Its torque rating exceeds 30 Nm, sufficient for standard glass panels up to 1.2 meters in width. The motor’s low‑profile design also reduces the overall weight by roughly 3 kg compared to older mechanical regulators.
