GM 88861355 Fuse,Maxi 50 A

The vehicle's electrical circuits are saved by fuses. When there is an excessive current in the circuit, it will cause the fuse element to melt and thus stop the flow of current. Each Devilles and Fleetwoods have a fuse block that is located under the left hand side of the instrument panel. Also, a 1991-93 model Deville and Fleetwood are equipped with a fuse block that can be found at the rear of the engine compartment. In Eldorado and Sevitte, this is in a glove box behind an access panel. For 1992-98 Eldorado and Seville, there are two fuse blocks, one located on the left side of the engine compartment, on the wheelwell and one located on the side of the trunk. To check whether or not a fuse is blown, remove it from its slot in the fuse block and look for a break in the center of its element wire. Should any break exist in it, replace it with another whose rating is similar to itself. It should also be kept in mind that it is essential to change a blown fuse with that which has got similar type as well as an equal amount of current rating. Installing a higher-rated fuse can lead to vehicle fire or personal injury as well as damages on your car.

The electrical circuits of the vehicle are safeguarded with fuses, circuit breakers as well as fusible links. In some of the earlier models, the passenger compartment fuse block can be found on the right side of the dashboard in a compartment under the instrument panel that can be accessed after removing the glove box insert. As for the later versions, the internal fuse/relay blocks are located even better: they are in a plastic lid at the right side of the dashboard, and you can get an access thereto by opening the right front door. The interior fuse panel however for later models of the Grand Prix can be located inside the glove compartment. Also in the right front corner of the engine room there is a second fuel cut-off block which is fixed under the protective cover which can be swung up for access. Other fuse blocks may also be included in the models and are normally located in the engine compartment. Every fuse works independently to protect a particular loop of the electrical system, and all the loops are labeled on the face of the fuse panel. Miniature fuses with blade terminal type are applied to the fuse block with the possibility of their manual withdrawal and insertion. When an electrical component is defective, it is wise that one checks the fuse first; among the simplest ways could be checking using a test light at the end of the terminal of the fuses. Thus, if there is power on one side of the fuse but not on the other side, then the fuse is blown - this can also be seen just by eye, as the element in between the terminals melts when a fuse blows. Blown fuses should therefore be replaced with fuses of the correct type since although fuses come in different ratings that are physically interchangeable they should not be swapped since each electrical circuit needs a specific amount of protection; the amperage value is molded into the fuse body. If a replacement fuse blows instantly, it should not be replaced again before the real problem, mostly a short circuit within the wires due to a bad or worn wire has been addressed.

If a replacement fuse immediately fails, do not replace it again until the cause of the problem is isolated and corrected. In most cases, the cause will be a short circuit in the wiring caused by a broken or deteriorated wire.

This can be done using a test light to check for power at the exposed terminal tips of each fuse. If power is present on one side but not the other, the fuse is blown. Blown fuses can also be visually inspected.

The instrument panel relay center is located beneath the steering column and requires the removal of the left side knee bolster and mounting bolts for access to the relays.

There are different sizes of fuses, including small, medium, and large, all with the same blade terminal design.

Circuit breakers protect specific circuits like power windows and power seats. They reset automatically, so if there is an electrical overload, the circuit will momentarily fail and then come back on. If the circuit does not come back on, it should be checked immediately. Using a voltmeter, each end prong of the circuit breaker should be tested for battery voltage with the negative lead on a good chassis ground. If there is battery voltage only at one end, the circuit breaker needs to be replaced.
