2009 Buick Lucerne with heated and cooled seats, the back of pass. seat not heating.
All the indicator lights work and all the heated seats work except the passenger back cushion. I have found out from the Buick dealer there is no heating pad (element) in the back cushion with heated and cooled seats, but a blower system that sends heat and cool to the back cushion. Before I dive into this problem, looking for advise and direction. Thanks, Joe
