The cruise control system in a 2004 Chevy TrailBlazer has two different fuses that control it. The first fuse can be found in the panel that is under the hood, and the second one is found in the fuse panel under the dash on the driver's side below the steering wheel. Both of these fuses control different parts of the cruise control system and are both needed to have it working properly. The one in the engine bay helps control the throttle response system, and the interior one goes to the controls and main computer for the system. If Your cruise control is not working then this is the first thing that You should check.
