• Durable Construction: Constructed from high‑grade aluminum alloy with reinforced plastic housing, the blower resists corrosion and thermal degradation over long service life.

Electrical Specifications

Installation Compatibility

The V20-03-1112 is engineered for direct replacement of the original interior blower in the BMW 3 Series E36 models, including:

• BMW 3 Series (E36) – Sedan, Cabrio, and Touring variants
• Year Range: 1990‑2000
• Engine Variants: 1.6L, 2.0L, 2.5L, and M3 3.0L (depending on HVAC configuration)

Installation requires standard automotive tools and follows the manufacturer’s wiring diagram for the HVAC system. The blower mounts using the original bracket set, ensuring a tool‑free fitment process.

Performance Benefits

• Enhanced Cabin Comfort: Reliable airflow improves temperature regulation, reducing cabin heat buildup during hot weather and maintaining cool air in winter conditions.
• Improved Air Quality: Consistent circulation helps distribute filtered air throughout the interior, minimizing stagnant zones that can harbor odors or contaminants.
• Energy Efficiency: The brushless design consumes less power than older brushed motors, contributing to overall vehicle efficiency and reducing load on the alternator.
• Longevity: With robust materials and low‑wear bearings, the blower maintains performance over extended mileage without frequent maintenance.

Maintenance Tips

1. Regular Inspection: Check for loose mounting bolts or signs of wear on the impeller blades during routine service intervals.
2. Clean Air Intake: Ensure that the blower’s intake filter remains free of dust and debris to preserve airflow efficiency.
3. Lubrication: Although brushless motors typically require no lubrication, verify that any bearing seals remain intact to prevent moisture ingress.
