Hi my name is***** will be glad to try to help. What are you getting for fault codes? Check all fuses and relays as well as safety switches such as lap bar, seat switch, or door switch if equipped. Try having the lift tile actuators recalibrated as well and let me know what you have for codes.
thanks for the update. I help on here in my spare time as well so no worries. We can post as needed. Check for power to the hydraulic control valve solenoids as it is possible you have a failed controller if the controller has safety switch engaged signal but not powering the solenoids to open up the functions. See if your dealer can bench test and reprogram your existing controller and see if it reveals a failed controller or resolves your issue. Let me know
