To troubleshoot, you should first check the power distribution box (often under the hood, sometimes in the passenger compartment). Look for fuses related to the powertrain or accessories. A blown fuse in one of *these* circuits could affect the cruise control's operation. The owner's manual is your best resource for locating the fuse box and identifying the fuses.
Instead of searching for a specific "cruise control fuse," focus on these:
* Check the fuses for the ignition system: If the ignition system isn't getting power, neither will the cruise control.
* Check the fuses for the powertrain control module (PCM): The PCM controls many aspects of the engine and transmission, including the cruise control.
If all the relevant fuses are fine, the problem lies elsewhere in the cruise control system itself, requiring a more in-depth diagnosis by a mechanic. Don't just start randomly replacing fuses – identify the potential circuits first.
