Like many others, the cruise control is not working on my Q45. I can turn the system on so that the CRUISE light comes on in the dashboard and if I press set the SET light lights up, but the cruise control still doesn't work. I know that it is not the brake switch as I can set the speed and the car will actually cancel if I press the brake pedal. I've already checked all the related fuses and they were good.

I'm at a loss as to what to check next. I used the FSM to check a few of the modules with a multimeter and the ones that I checked seemed ok but there were also ones that I couldn't get to. Anybody have suggestions for what I should do or check next?

FGY33 has mechanical cable that controls the throttle plate from the cruise actuator (black diaphragm). make sure cable is rigged properly.
