My steps would not lock in the open position. They would open and close when the door was opened or closed. While driving they suddenly opened. I was alerted by a trucker. Now I can't close them so...
I had a problem last year when my 3 steps would not retract. I disconnected the motor and then held them up with 2 large hose clamps on each sidearm. You will have to go underneath to do this. It made for a huge step but it was our last day on the way home.
