In this tutorial, we learn how to check the fuses in a Cadillac. First, open the hood of the car and look for the fuse box that is left to the engine. Now, open the clips on the fuse box and take the top off. You will now see a diagram of what all the different fuses of the car are and what they do. The big gray boxes are relays, which you most likely won't need to touch. The fuses are small little boxes that you can take out with a pair of pliers. If a fuse needs replaced, you will be able to see that the middle of the fuse is black and broken. Simply replace this with a new fuse and replace the top of the box when finished.
