Ok postoak213, here is the next idea. The cruise control will send DTC's (trouble codes) if it is not working. You can display the codes on the LCD display on your dash. Here is the post where I explained how to retrieve information and display it on the LCD display, http://fordtransitconnectforum.com/topic/636-fuel-mileage-display/#entry4606 , position 9 holds the DTC's. P0579, P0581, P1572, and P1703 are the four DTC's for the cruise control. If any of those codes show up, Google them for a description of what is wrong. Good Luck!
