Call the dealer. Most valuable phone number when you buy a new coach is the service manager's phone number. Next is the JC customer service number.
Battery condition? Front running off TV - rear off battery and they are dead? crazy, but maybe?
As suggested, a fuse.
Can you manually run them down. That may release a bind and get all moving again.
Have you operated them prior? Is this a mfg fault? Are they even connected?
Has anyone suggested yo call the dealer or JC.
. Hope you get it figured. Bummer. Pat
