To find the potential culprits, you need to consult your owner's manual. It will have a fuse box diagram showing the location of all fuses and relays, and often lists what circuits each fuse protects. Look for fuses related to:
* Power distribution: A blown fuse in the main power distribution system could prevent power from reaching the cruise control.
* Body control module (BCM): The BCM controls many vehicle functions, including cruise control. A fuse protecting the BCM circuit needs checking.
Important Note: The fuse box location varies slightly depending on the trim level and whether you have a standard or extended cab. Your owner's manual is the definitive source for your specific truck's fuse box locations and diagrams.
If you can't find the problem through checking fuses, the issue is likely more complex and could involve faulty wiring, a malfunctioning BCM, or even a problem within the cruise control system itself, necessitating a visit to a mechanic or auto electrician.
