Question about 2004 GMC Sierra 2500
Though I'm not familiar with the Diesel, most vehicles have two throttle cables. One is for the cruise and it's common for the plastic part at the end (throttle body) to break. This is the easiest fix, and very commonly the problem. Good Luck

SOURCE: cruise control does not work
Have you had this campaign done yet?
06030: Product Safety - Brake Lamps Inoperative or Continuous Illumination
If the switch is malfunctioning the cruise control will not engage.

try lifting the brake pedal with your toes then switching on the cc when driving. sometimes a faulty or loose switch on the brake pedal can cause cc to cut out.

May want to look at replacing the wiper circuit board.It is located on the firewall adjacent to the wiper motor and has a some what square black cover with 3 torx screws and wireing harness pluged into the side.We had a truck that every time you washed it the wipers would stay on until it dryed out.You can try removing it and spaying it down with contact cleaner just watch the brease on the two contact tips.Well hope this helps.

SOURCE: I have 1998 gmc 3/4 ton auto . a.b.s light comes on intermitantly. when it does I also loose my full heater controls and cruise control. new brake switch has been instaled but c'ant see how that would
It is coincidence that your heater control went at the same time your ABS control went out. Try replacing the ABS control and see if that fixes it. Many times because of the electrical complexity you have to just start replacing things until you get it unless you own one very expensive computer.
Look for loose wires. Also try it in reverse if you like. Replace the heater control and see if that fixes it all. Also check ALL fuses.
