No power to slide outs

O.K... Is this New to you, or have you had this MH for a while? Did this just happen? Was their any signs of problems before the slides quit working? If this problem has just developed, it could be a bad connection to the switches, or the control box for the slides. After long periods of non use the switches can form corrosion on the contacts. Sometimes just using them a lot will clean them to allow them to work.
