An air dam deployment and retraction system includes an air dam, a compressor, an air reservoir, a first switch, a second switch, and a third switch. The air dam is configured for moving between a deployed position and a retracted position. The compressor is configured to compress fluid. The air reservoir defines a chamber that is configured to receive a volume of the compressed fluid. The first switch is configured to selectively move between a first inactive position and a first active position. The first inactive position is configured to provide the compressed fluid to the atmosphere. The first active position is configured to provide the compressed fluid from the compressor to one of the chamber of the air reservoir and the air dam. The air dam is configured to move from the retracted position to the deployed position upon receiving the compressed fluid.

Air dam deployment and retraction system

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.
