Most people think that their car has a fuse for the blower fan, but in reality, there is no such thing. The only fuses in your car are for things like the headlights, taillights, and engine. So if your blower fan isn't working, it's most likely because of a problem with the motor itself or a loose wire. If you're not sure how to fix it yourself, you can always take it to a mechanic and have them take a look at it.
