Lift will stop going forward or reverse after shifting from either one. This is an intermittent problem. You have to turn key off then back on to get it to reset. I have changed out E-brake switch, seat switch. Thinking it was one of them. On my main controller the green light will flash 3 times then a pause then 3 times again keeps repeating till key is turned off then on. I am assuming the flash I am seeing on main controller is same as I would see on dash. If the light was still intact.
