Hey guys, my 91 Ram 250 w/ Cummins Turbo Diesel is having cruise control issues. That wouldn't be a problem if it wasn't I have to drive it from Texas to Seattle in two days pulling a trailer. The drive down was hell, I had to fight the governor on the hills with the O/D switched off. I replaced the switch in the steering wheel as it was clearly worn but still nothing. The control unit has power and vaccum. As I am far away from my shop I have no manual so any help would be greatly appreciated. Thanks a million!
