I had a SiriusXM satellite radio installed in my 2008 Clubman S and since then the AC vent selection is off. When I push the dash vent button the air comes out of the foot wells. The foot well button activates the defroster vents and the defroster vent button activates the dash vents. I have searched for any information on this and have been unable to locate any similar problem or a fix. Has anyone else experienced this problem and hopefully have a solution?
