I purchased a 1999 Dodge 3/4 with cummins 4x4 and have not been able to get the cruise to work. I have fixed and checked the vaccum line to the controller under the battery. I have replaced the clockspring. I have no lights on on my dash and no DTC codes showing up when I turn the key on and off 3 times. I have checked all the fuses in the cab and under the hood (they are all good). It seems I have no power to the cruise. I have never seen the cruise light come on. I am driveing to NC from KS this next weekend and sure did want to use the cruise for the 18 hour drive. If anyone has any other ideas I'm all ears. I do not have any schematics of the system to isolate the power source and voltages/amps. Thanks for looking I hope someone can help, everything else on the truck works as far as I know. I haven't had it too long.
