2nd Gen Non-Engine/Transmission cruz control quit

[highgear]

i have a 99 dodge 3500 4x4 and the other day i turned on the cruz control and set the speed and the cruz didnt work, i stopped and went into 4 wheel low settings ,and the vacuum pulled the front axle into the proper settings, i dont think its a problem with the vacuum sys. i then looked for a fuse in the cab and then under the hood fuse box and found nothing. so where do i go from here. any ideas thanks

At what speed did you turn on the cruise control? On my 2nd gen Dodge/Cummins, I would have to be going 35 mph or faster before the cruise control would work.
