I just purchased a 95 xlv marathon coach, I am new to this board or group... doe anyone know how to turn on the lights on the wall in the area where the coaches are? I believe they are 110v , all the breakers are on.. the master switch is on next to the pass seat, I think I have turn or pushed every button .. no lights .... I have got the lights that are mount in the ceiling to come on . also how does the tilt wheel tilt...
