I have a 2011 Winnebago Vista 35 F that has a dual rail FLS/RPD DigiSync control system. The system has become unresponsive. Coach is level, engine is running, battery voltage is good. Slide locking motor operates properly. Unlocked slide, but when I press the Out (or In) button, nothing happens. No sound, no lights, just nothing. Rear slide works properly, but is single slide, with a different switch. The DigiSync is acting like there is no power. None of the lights light up or flash. It's just dead. I have checked all breakers, both inside and out of the coach and none have required a reset. Any suggestions on where to look next?
