I suspect I have a bad air switch for the cruise control on a new-to-us 2008 M2 straight truck. We have three other M2s, and the pressure switches are all on a module either in the middle of the cab below the dash or right above the accelerator pedal. This one is in neither of those places, and I've completely torn apart the dash looking for it. I can't find anything online that tells me where it might be. Any help would be greatly appreciated.
