To troubleshoot, you should:
1. Consult your owner's manual: This is the best resource for your specific vehicle's fuse box layout and fuse descriptions. Look for fuses related to the power distribution and possibly the body control module (BCM).
2. Check the fuses visually: Even if a fuse isn't specifically labeled "Cruise Control," inspect all fuses in the underhood and interior fuse boxes for any that are blown (broken filament). Pay particular attention to any fuses related to power distribution or body control modules.
3. Have the system diagnosed: If you can't find a blown fuse, it's best to take your Excursion to a mechanic or auto parts store with diagnostic capabilities. They can use a scan tool to check for diagnostic trouble codes (DTCs) that might point to the actual problem.
Simply replacing fuses randomly without a proper diagnosis could cause further damage.
