An exemplary vehicle flow influencing assembly includes a deflector formed together with a seal that provides a portion of a glass run for a side window of a vehicle. The deflector projects outward from the vehicle when the side window is lowered such that the deflector influences flow over an opening to a passenger compartment of the vehicle. A vehicle flow influencing assembly includes a pillar that is directly forward a side window of a vehicle, and a deflector configured to influence flow over an opening to a passenger compartment of the vehicle. The opening is provided by positioning the side window in an open position. The deflector extends longitudinally in a direction aligned with the pillar. The deflector projects outward from a primary surface of the pillar when the side window is closed and when the side window is open.
