Lightnbolt you have to access the controls. Cables 17 & 14 are attached to air distribution switch. Very much possible that one of the cables is bent or poped out from its bracket or the bracket is broken. The bracket is a small plastic piece that attaches the cable to the switch.
I had a similar issue. After reaching the switches I discovered that cable 14 was dislodged from its holding bracket. All I had to do is pop it back in.
