A ventilation module for a vehicle having a housing including a flap hingedly secured along an inner edge to the housing to extend across its open interior. The flap includes side edges and an interconnecting outer edge which contact, in a closed flap condition, support locations configured along the housing to define its open interior. One or more fingers extend from at least one of the side and outer edges of the flap so that the fingers abut standoff locations of the housing located in proximity to the support locations. Upon a sufficient positive air pressure condition created within the passenger compartment which overcomes a holding force exerted by the fingers against said stand-offs, the flap is allowed to open in a controlled fashion to vent to the exterior the excess air pressure, until reclosing upon achieving an air equilibrium condition.
