I left the driver's side rear seat up out of the way for a few days to make room for my bike. When I returned the seat to it's normal position I am noticing that the spring that returns the seat from flat to upright will barely lift the seat at all. It seems that the return-spring is sprung. Has anyone else run into the same problem? One would think that the return spring should be rugged enough to handle a flat out position for a few days without being ruined. Any thoughts? :?
