To find it, you need to:
1. Consult your owner's manual: This is the most reliable source. The manual will have a diagram showing the fuse box layout and what each fuse controls.
2. Check both fuse boxes: Look under the hood and under the dashboard (often near the steering column). The fuse boxes will have covers with diagrams showing which fuse controls which circuit.
3. Look for a fuse labeled "Interior Lights," "Dome Light," "Courtesy Lights," or a similar designation. The amperage rating may also be listed (e.g., 10A, 15A).
4. If you can't find it using the diagram, try removing a fuse with a similar amperage rating and testing the lights. Replace the fuse immediately if it doesn't solve the problem. Never attempt this without the correct amperage. Using the wrong amperage fuse can damage electrical components.
Without your specific Transit model (e.g., 250, 350, etc.) and trim level, providing a more precise location is impossible. Using the owner's manual is the best and safest approach.
