I would think if steam is coming from your vents that you have a leaking or defective heater core and or one of its components and in most cases the water leaking from the core can be found in the floor board on the passsenger side and this needs to be fixed right away due to engine coolant loss and the possiblity of engine damage from overheating. Also if the air conditioner developes a leak it could be mistaken for steam however if the freon is lost the ac will quit. , EzForJesus
heater core..
The steam could be coolant from a bad heater core.
If the vents are inside the cab of the truck, this could mean you have blown your heater core.
The magma gushes out and then it flows every where. The volcano has vents that let air come out. When the vents open steam/ smoke comes out of those vents.

Heating hoses are exposed and need to be replaced. The heater core is leaking coolant.
The heater may not be on - but the fan still blows air through the vents when they're open !
Vents in the volcano are passage ways for the magma, steam, and heat to escape the earth.
