MC Cruise problem
looking for a little help about MC cruise. i have 2011 X1 with MC cruise and the speed control switch is not working; the switch with the "+" & "-" on it. the cruise turns on & off as it should and it engages at the set speed as it should. the crazy part is i can adjust the speed with the display selector switch. this is the switch that toggles the display between engine hrs, air temp, water temp etc. the wires are connected properly to the "+" & "-" switch. i haven't taken the dash apart to look at the display wire connections. are these two switches connected somehow? anyone have any suggestions on how to make the "+" & "-" switch work again before i start taking the dash apart?
