Tesla Model S/X (2016-2021) Heater Blower Motor with Fan (1051864-00-A) | OEM-Equivalent Climate Control Solution
Revitalize Your Tesla’s Cabin Comfort – Engineered for Precision and Longevity
Why This Blower Motor is Critical for Model S/X Owners
The 1051864-00-A blower motor is the beating heart of your Tesla’s HVAC system, responsible for circulating heated or cooled air throughout the cabin. Unlike generic aftermarket alternatives, this OEM-equivalent part is designed to meet Tesla’s exacting standards, ensuring seamless integration with your vehicle’s climate control software and hardware.
Model-Specific Compatibility: Exclusively engineered for Model S (2016–2021) and Model X (2016–February 2021), eliminating fitment guesswork .
Complete Assembly: Includes the motor, fan blade, and resistor controller in a single unit, saving hours of labor compared to sourcing components separately .
Core Functions and Performance Metrics
This blower motor delivers precision climate control through:
Rapid Airflow: Generates 1,100 CFM (cubic feet per minute) of airflow, capable of adjusting cabin temperature by 10°C in under 2.5 minutes (tested in Model S 2018) .
Dual-Zone Optimization: Works in tandem with Tesla’s dual-zone system to direct air independently to front and rear vents, ensuring passenger comfort across all seating areas.
Defrost Efficiency: Clears windshield frost in 45 seconds at maximum fan speed, a critical safety feature for cold-weather driving .
Signs of Impending Failure – Act Before It’s Too Late
Don’t ignore these red flags:
Reduced Airflow: Vents emit weak air even at maximum settings, often caused by worn fan bearings .
Grinding Noises: Metallic grinding or squealing from behind the dashboard indicates internal motor damage .
Intermittent Operation: Fan cuts out at low speeds but works at high settings, signaling failing motor windings .
Error Codes: “HVAC Fan Fault” or “Blower Motor Malfunction” alerts on the touchscreen .
Engineering Excellence: Matching Tesla’s Original Standards
Brushless Motor Design: Features a 12V brushless motor (vs. cheaper brushed motors) for 80,000+ hours of operation – equivalent to 12+ years of daily use .
Balanced Fan Blade: Injection-molded ABS fan with aerodynamic curvature reduces vibration and noise to 60dB at maximum speed (15dB quieter than generic aftermarket motors) .
Water Resistance: IP6K7-rated housing protects against moisture ingress, critical for Model X’s front trunk drainage system .
DIY Installation Guide (45–90 Minutes)
Most Model S/X owners can complete this swap with basic tools:
Safety Preparations:
Disconnect the 12V battery (located in the frunk for Model S/X) and wait 10 minutes for residual power to drain service.tesla.com.
Access the Motor:
Model S: Remove the glove box and HVAC cover behind the dashboard’s passenger side .
Model X: Disassemble the right-side footwell trim and remove the HVAC housing bracket.
Component Replacement:
Unplug the 3-pin electrical connector and remove 4 T25 Torx screws securing the motor assembly.
Transfer the resistor controller from the old motor to the new unit (if applicable) .
Post-Installation Testing:
Reconnect the battery and test all fan speeds. The system will auto-calibrate without need for diagnostics .
Pro Tip: Apply dielectric grease to the electrical connector to prevent corrosion in high-humidity environments .
Warranty and Included Components
2-Year Warranty: Covers defects in materials and workmanship, with free replacement for non-repairable failures .
Complete Kit: Includes the blower motor, fan assembly, resistor controller, and a PDF installation guide with Model S/X-specific diagrams .
Why Choose OEM-Equivalent Over Aftermarket
Aftermarket motors often fail within 6–12 months due to:
Inferior Bearings: Generic motors use low-grade steel bearings that wear out quickly under Tesla’s high-load HVAC system .
Software Incompatibility: Aftermarket parts may trigger “Fan Fault” errors due to mismatched voltage ratings .
Noisy Operation: Generic fans produce up to 75dB of noise at max speed, disrupting cabin quietness .
