* Nothing: Many vans have completely empty space under the seat.
* Storage: A simple, un-insulated storage container for small items.
* Electrical components: Fuses, relays, or other electrical parts for the vehicle's systems.
* HVAC components: Parts of the heating, ventilation, and air conditioning system.
* Part of the seat mechanism: The box might house parts of the seat's adjustment or folding mechanisms.
To know for sure what's in the box under the driver's seat of *your* Dodge van, you'll need to:
* Consult your owner's manual: This is the best resource.
* Visually inspect it: Carefully look under the seat to see what's there. (Be careful not to damage anything.)
* Look online for your specific van's year and model: Search for diagrams or photos of your van's interior.
Without knowing the specific year, make, and model of your Dodge van, it's impossible to give a definitive answer.
