Have a 1997 Dodge Ram 1500 5.9L 4x4 -- Cruise control lights up, but will not engage when push button on steering wheel. I replaced the servo today. Still nothing. A tech told me that my vacuum lines are fine and there is no tears or obvious holes or damage to lines. Checked fuse box, but there is no fuse for cruise control. I may have a bad ABS sensor as the light just for the ABS comes on intermittently. Light comes on about 10-20 minutes after driving, but always is off when restart truck. Could this error really cause my cruise control not to work????

Everything else looks fine around cruise control servo, no damage to wires or vacuum lines. Can someone else help guide me thru to another possible solution.
