    Doesn't on Fresh air setting. AC is still working, relay just intermittently chatters while selected to Recirculation. Any ideas? Thanks.

    I've no idea. Vent still flows air continously regardless of preference. The chattering is a little unnerving. It's like listening to a drummer that can't keep a Beat
