In my 2016 the loft bed controller is in the cabinet above the drivers seat. Reset directions are on the controller. (It is mounted upside down so I took a picture and rotated it to read them. Once I reset it works fine.
My panel lights did the same thing. I used the brightness switch and made it brighter and that fixed them.
There is an stock air mattress that comes with the coach for the sofa bed. If you need to purchase one Wal-Mart Intellex(?) Queen size works well.
