Well thanks for the info. I changed the brake lights and the overhead cab brake light, No luck. Cruise control still not working. It does not have a direct fuse for it, is there any other fuse I should check. I read somthing about the shift interlock switch being bad. What is that, and where is it on the truck. Thanks for the help.

Change the two rear taillight/brakelight bulbs if they are old. You may have a filiment on on of the brakelight bulbs that's burnt. The cruise "triggers" on the voltage drop of the brake lights when the pedal is applied. When the brakes are off, and you are cruising above 35 MPH, the cruise will activate.
Check the overhead cab brake light as well. Is that an LED replacement?
