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 and, or the diagram on the fuse box lid or the fuse label, 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.
- Turn the ignition switch to the LOCK (0) position. Make sure the headlights and all other accessories are off.
- On the under-hood and passenger side interior fuse boxes, remove the cover from each fuse box.
- Check each of the large fuses in the under-hood fuse box by looking through the top at the wire inside. Removing these fuses requires a Phillips-head screwdriver. Also, check the combined fuse box in the under-hood fuse box.
- Check the smaller fuses in the under-hood fuse box and all the fuses in the interior fuse boxes by pulling out each fuse with the fuse puller provided in the under-hood fuse box.
- Look for a blown wire inside the fuse. If it is blown, replace it with one of the spare fuses of the same rating or lower. Your vehicle has spare fuses on the back of the under-hood fuse box cover.
If you cannot drive the car 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. Make sure you can do without that circuit temporarily (such as the cigarette lighter 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. - 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 technician.
Notice
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.
