How to Change an Electric Fuse
- 1). Stop the car. Usually when a fuse blows some system on your car will stop working. It may take you a moment to figure out which system it is but you should pull over at a safe place and turn the car off. Turn off all the accessories on the car. Start the car, go through the systems one by one, and try to find which system is not operable.
- 2). Locate the fuse that controls the system that doesn't work. There are two places where the fuses for your car are located. One is on the driver's side of the car below the dash on the side of the car. It will be very close to where your knee would be. Open the cover over the fuses and look inside the cover to find what each fuse is controlling. If you find the fuse of interest then pull the fuse from the socket it is in. There are two types of fuses used in cars. One is a long cylindrical glass tube with metal ends. There is a filament of wire running from one end to the other. The other type is a spade fuse. These have two spade connectors sticking out of a piece of colored plastic. In the plastic, there is a piece of metal connecting the two spade connectors. If the piece of metal connecting the two ends is broken or burnt, then the fuse is blown and you must replace it.
- 3). Obtain a replacement fuse of the same type. The plastic spade type fuse has a number written on the top of the plastic. This is the voltage rating of the fuse. On the glass tube type fuses, the voltage is marked on one of the metal ends.
- 4). Replace the fuse and put the cover back on. The other location of fuses is under the hood of the car and also has a cover. The procedure is the same to check and change a fuse in this location. For spade type connectors, one of the locations of fuses has a fuse puller that will slip around the top of the fuse and help pull the fuse from the socket.
