Checking and Replacing Fuses in Toyota Corolla

If the headlights or other electrical components do not work, check the fuses. If any of the fuses are blown, they must be replaced.

Determine which fuse may be causing the problem. The lid of the fuse box shows the name of the circuit for each fuse. Turn the ignition switch and inoperative component off. Pull a suspected fuse straight out and check it. If the fuse has blown, push a new fuse into the clip. Only install a fuse with the amperage rating designated on the fuse box lid.
