Have a 2006 Allegro Bus and the electric steps will not come down for several days then one day you will open the screen door and they will come out on their own.?

The intermittent issue with your 2006 Allegro Bus's electric steps could be due to a faulty switch, wiring problem, or a malfunctioning control module. It's possible that vibrations or temperature changes are temporarily allowing the system to work. Inspect the switch and wiring for any signs of wear or damage, and consider checking the connections. If the problem persists, consulting a professional technician may be necessary for a thorough diagnosis.
