Abstract
A valve flapper door return spring mechanism for an automotive HVAC housing is modified so as to compensate for tolerance variations, so that the door is held in a substantially rattle free return position regardless. One of a pair of resilient spring fingers sits in a V shaped notch created by the intersection of a pair of spring finger stop surfaces that are opposed in slope. The one spring finger can therefore continually seat itself into an equilibrium position at the bottom of the V, and always make solid contact.
