First off Welcome to the forum
Secondly: you shouldn't have left the dealership with a non operating touch pad. They are universal and the service person should have swapped it out with another one and then ordered a replacement. These type of posts get under my skin and just point out the fact that there are some LOUSY dealers out there.
Anyway, sorry for the rant...Lets address your issue. Is the leveling system electric (ground control 3.0) or hydraulic (level up) and is it ted to any remote like One control or InCommand?
