To answer this properly, certainly we need to know the year, make and model of your car.

The fuse box is usually on the driver side under the dash. When you pull the cover, on the back of the cover is a list of what fuses control what equipment

Depends on the car. It'll be inside the cabin, check glovebox, under drivers side dash, open door and check drivers side and passenger side of dash.
