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
