Checking and Replacing Fuses

If something electrical in your vehicle stops working, the first thing you should check for is a blown fuse. Determine from the chart, or the diagram on the fuse box lid, which fuse or fuses control that component. Check those fuses first, but check all the fuses before deciding that a blown fuse is not the cause. Replace any blown fuses and check if the device works.

  1. Turn the ignition switch to LOCK (0). Make sure the headlights and all other accessories are off.
  2. Remove the cover from the fuse box.
  3. Check each of the large fuses in the under-hood fuse box by looking at the wire inside.
  4. Check the smaller fuses in the under-hood fuse box and all the fuses in the interior fuse box by pulling out each one with the fuse puller provided in the under-hood fuse box.
  5. Look for a burned wire inside the fuse. If it is burned, replace it with one of the spare fuses of the same rating or lower.
    If you cannot drive the vehicle without fixing the problem, and you do not have a spare fuse, take a fuse of the same rating or a lower rating from one of the other circuits with the fuse puller provided in the underhood fuse box. Make sure you can do without that circuit temporarily (such as the accessory power socket or radio).
    If you replace the blown fuse with a spare fuse that has a lower rating, it might blow out again. This does not indicate anything wrong. Replace the fuse with one of the correct rating as soon as you can.
  6. If the replacement fuse of the same rating blows in a short time, there is probably a serious electrical problem with your vehicle. Leave the blown fuse in that circuit, and have your vehicle checked by a qualified mechanic.

Replacing a fuse with one that has a higher rating greatly increases the chances of damaging the electrical system. If you do not have a replacement fuse with the proper rating for the circuit, install one with a lower rating.
