Primary OE reference: 4H1820021A
Cross-reference 1: 4H1820021B
Cross-reference 2: 4H1820021C
Product type: Automotive HVAC Blower Motor
Applicable vehicle: AUDI Phideon 2012-2018
Brand: AUDI
Model: Phideon
Vehicle year: 2012-2018
Electrical match: Confirm voltage, plug key and terminal count against the original motor
Motor interface: Compare flange contour, screw spacing and motor-body depth
Fan wheel check: Verify wheel diameter, height and rotation direction before ordering
HVAC function: Cabin airflow depends on the motor, fan wheel, resistor or controller, wiring and an unobstructed filter working together.
Installation guidance: Inspect the resistor or electronic controller and connector terminals if the original fault involved intermittent speed operation.
Fitment basis: Check voltage, rotation direction, cable exit and the position of every locating tab against the existing blower.
Quotation information: Provide the OE number, vehicle application, quantity and delivery country
