1994 Chevy Lumina Fuses

Your fuses are located inside the fuse boxes (in your engine compartment and inside the car).
To pull a fuse, you can use a special tool but it is not necessary (it's easier though).
To check your fuses, you can either pull each one out and visually inspect them, or use a test light.
Fuses are transparent and have a wire in the middle; if the wire is burned, your fuse needs to be replaced.
Usually, when you have a blown fuse, it means that this particular circuit experienced an overload or there's a short. So replacing the fuse might only be a temporary fix.
