Your best bet is to consult your owner's manual. It will have a fuse box diagram showing the fuse numbers and what circuits they control. Look for fuses labeled "tail lamps," "stop lamps," "park lamps," "turn signals" (as these often share circuits), or something similar.
Location of Fuse Boxes: The 2001 E350 likely has multiple fuse boxes:
* Under the hood: This is the most common location for a large fuse box.
* Inside the cab: There might be a smaller fuse box (often under the dash, possibly near the steering column).
Troubleshooting:
1. Check your owner's manual first: This is the most accurate source for your specific vehicle.
2. Inspect the bulbs themselves: A blown bulb is the most common cause of a non-working light, even before looking at fuses.
3. Systematic Fuse Check: Start with the fuses related to the taillights. Carefully check each fuse with a test light or by removing it and visually inspecting it for a broken filament. Remember to replace fuses with the correct amperage.
4. Wiring: If all fuses are good and bulbs work, there might be a wiring issue, requiring more specialized troubleshooting.
Without the owner's manual, I can't give you the specific fuse locations. Please find your owner's manual for precise information.
