* Under the hood: This is the most common location for the main fuse box (often called the power distribution box). Look near the battery, often on the driver's side fender well. It's usually a large black plastic box.
* Inside the van, typically under the dash: There's often a smaller fuse panel inside the van, usually located under the dashboard on the driver's side. This panel will handle smaller circuits within the passenger compartment.
To be sure:
1. Consult your owner's manual: If you still have the original owner's manual for your van, it will definitively show the location(s) of the fuse boxes.
2. Check the van's fuse box cover: If you find a fuse box, the cover itself may have a diagram showing which fuse controls what circuit.
3. Look for labels: The fuse boxes themselves may have labels indicating what they are.
If you can't find it using these methods, a detailed image search online for "1996 Ford E-150 fuse box location" might reveal photos of the fuse box in similar vans. However, remember that variations exist between conversion vans.
