Abstract
A vehicle has an inflatable air dam assembly that is deployed and stowed by a bidirectional deploy/stow system. The deployment and stowing may be based on vehicle speed. The deploy/stow system includes an air compressor and first and second valves for directing air into and out of the air dam assembly. The compressor operates on both deploy and stow operations to fill and evacuate, respectively, the air dam assembly.
