Heater
Was driving down the road yesterday and my heater just shut off. I tried turning it on and nothing I can go from low to high and nothing. I turn it from feet to defrost and nothing. Any idea what I should check out? It's cold in SD right now...

Pretty much this. If it's not the fuse then it's likely the blower motor. Usually you can clean up the brushes on the blower motor and it'll work again (for a while)

But checking that fuse is SUPER easy.

Well if the motor is out, it won't matter if you switch from defrost to floor with no air moving. So i would venture to guess that the motor is out, the resistor its blown, or the fuse is crapped out. Or the blower switch itself.
