Put the heater in the defrost mode, thatís the best way to get floor heat in a Seneca. I canít explain it but we departed Minnesota 4 days ago and were driving through Iowa where the outside air temp was 9F. The cab was warm but our feet were cold. Played with the heat selector and found the best way to get heat to the floor is by selecting Defrost !!! Does not make sense but it worked.
