House: check fuse or breaker. Its usually on a separate circuit than than the rest of the house, so you might not notice if it tripped.

Car: Again, fuse for the blower circuit, or the speed control resistor. If the fuse is good, try the blower on the highest speed setting. If that works, its the resistor.

Since you're not a tech, you would be playing guessing games with your money. But my guess is that it's either the blower, or the circuit board. Take the problem to a trained tech.
Call a heating and air condition co. First look the company up in the yellow pages. Go to BBB and check to see if the company has a good standing.
I fixed my sons once, it was the circuit board. It could also be the transformer. There are many things. Take the two main wires to the blower... Look at the schematic and find out the two run wires to the blower motor. Power, and common. Put a reg 110 cord, with two alligator clips on each end of your 110 test wire. Take a cord off of a old iron, or something that no longer works in your house. Strip the wire on each end of the test cord, ad a alligator clip to each end and wrap with electrical tape.
Now you have a test wire. Keep it for future use. Put one alligator clip on the power wire, that wire should be black . And the other on the common wire, that wire should be white, But please look at the schematic it will tell you the two colors or the run wire. Turn off the breaker to the Heating unit. Then plug the 110 test cord into a 110 plug. If the blower comes on it's not the blower. It's the transformer, or the circuit board.
If it's your car, it's in the thermostat. It's not opening up to let the anitfreeze go through the engine. Or it could be a fuse.

Does the blower work for the a/c? If no, then check your fuse. Otherwise the blower motor may be siezed or blown. (this happens frequently on some makes/models)

Check to see if the fuse is blown or the circuit breaker is popped. If so, restore it & see if that fixes it. If not, call a repairman. If it happens again, call a repairman.

Furnaces should be checked out by a technician at the start of each heating system to avoid killing yourself with carbon monoxide when the burners get dirty, or in case there is a leak, etc.

check the fuse for the blower first,then if its good you probably ave a blower motor resister gone bad on it,that will knock out all speeds to the heater,a bad switch will also cause this to happen,if you don't find the problem you may have to get a shop to diagnose this for you,good luck with it.

Of course you need to check for a blown fuse, but your blower motor may need replacing unless it still runs on the high speed only in which case you need a new resistor pack.

I am guessing gas or oil. Blower won't go on unless there is a fire going in the burner area. Controlled by thermostat and the gas valve and ultimately by the gas/oil company(pay the bills and they will deliver) - also they may check your unit out to see what is up.

Car or home? If the former, check the blower fuse.

is there a fuse that controls the electrical aspect of the blower?

I'd call a repair man ASAP! Especially if you live in the midwest!!! I certainly wouldn't try and fix it yourself. It can be both very dangerous AND expensive. Certainly not worth the risk!
