    sorry i have a 2002 freightliner century my cruise control dosent work either i think it has something to do with my tach not working. This is my first truck and im waiting for all the paper work to go through. Im thinking of replacing the tach with a new one i hope that will fix the cruise control too.

    Maybe the pickup sensor has vibrated loose. The ones I've seen use a locknut to hold it once the depth is set. You loosen the locknut, then screw in the sensor by hand till it contacts the teeth it is sensing, then unscrew it a fraction of a turn (not sure what yours would be) and then tighten the lock nut to hold that setting. Also, check the wiring at the sensor as this is a more common place to break.

    Ty for the reply do you think that is the reason why the cruise control is not working?

    The cigarette plug thing i looked for the fuse in the passenger side dash and the fuse is still good. I think i gotta find where the wire goes. Is there another fuse box that i dont know about?
