Cross-reference 1: 8D1820021C
Product type: Automotive HVAC Blower Motor
Applicable vehicle: AUDI A6
Brand: AUDI
Model: A6
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: When the climate-control circuit commands airflow, the electric motor rotates the fan wheel inside the HVAC housing.
Installation guidance: Support the motor during removal, keep wiring clear of the wheel, and test all commanded fan speeds before refitting panels.
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
8D1820021A Automotive Blower Motor Overview
For cabin heating, ventilation and air-conditioning repairs, 8D1820021A is presented as the primary lookup number.
For catalogue item 6233-013, Stable wheel rotation helps distribute air without relying on vehicle speed, making the 8D1820021A blower important at idle and in traffic. Use 6233-013 when comparing this 8D1820021A airflow configuration.
OE Reference and Application
The primary catalogue number is 8D1820021A. The recorded application is AUDI A6. For 6233-013, Match the 8D1820021A motor body depth, flange shape, connector lock and impeller profile instead of relying on the listed AUDI vehicle name alone. Record 6233-013 with the approved OE reference.
HVAC Interface and 8D1820021A installation
During work on 6233-013, After 8D1820021A installation, operate low through high speed and confirm 8D1820021A airflow reaches the selected vents without abnormal vibration. Recheck 6233-013 before the lower trim is closed.
For item 6233-013, confirm that the 8D1820021A centrifugal wheel clears its housing and that the 6233-013 connector lock engages without force. After seating 6233-013, test the available fan speeds and listen for rubbing, imbalance or intermittent electrical operation linked to 6233-013.
