To find the correct fuse:
1. Locate your owner's manual: This will have a diagram showing the fuse box locations (usually under the hood and possibly in the passenger compartment) and a legend identifying which fuse controls what. The manual will specifically list the fuse(s) for the brake lights.
2. Check both fuse boxes: The Expedition likely has two fuse boxes, one under the hood and one inside the passenger compartment. Check both.
3. Look for labels: The fuses themselves or the fuse box cover might have labels indicating their function.
Without the owner's manual: It's difficult to give you a definitive answer. Searching online for a "2007 Ford Expedition XLT fuse box diagram" might yield a diagram, but using your owner's manual is always the most reliable method.
Important Safety Note: Always turn off the ignition before working with fuses.
