FAQs

Where can I find fuse diagram for my car? ›

To locate the fuse specification chart for your vehicle or to learn how to change a fuse, refer to the "Fuses" section of your Owner's Manual.

There are two fuse boxes, one located near the engine or under the hood and the other is located near the driver seat. The car fuse box under the hood protects engine components including engine control unit (ECU), cooling fan, ABS motor and battery.

The correct fuse for the tail light/running lights for the trailer on your 2011 Ford F250 Super Duty is fuse #30 (15 AMP) which is located in the interior fuse panel (Body control module).

It is fuse f2. 27 in the fuse box in the dash, 15amp.

In most cases, the main fuse box is situated under the hood, near the battery, while secondary panels can be found in the passenger compartment, often hidden behind a removable panel.

Small fuses generally identify the element speed using markings such as F, M, T etc, whilst larger fuses identify the element speed using markings such as gL, gG, aM etc. Some fuses use terms such as slow acting, fast acting, motor rated etc.

The ECM 1 is one such computer; it has a fuse is installed to protect the computer from sudden power surges or other component damage -- the fuse will blow before any damage can reach the ECM. Many component defects can cause your ECM 1 fuse to blow.

Still gripping it with the puller, hold the fuse up to the light (or a light source) and look through the translucent bodywork. You should see a thin metal wire in there. If the wire is no longer a continuous thread and appears broken or in two pieces, the fuse has indeed 'blown'.

An ACC fuse, also known as an accessory fuse, is a switched fuse that provides power to accessories such as the radio, power windows, and interior lights. It is typically used for devices that require power when the car is turned on, but not when it is turned off.

The DRL warning light, also known as the daytime running lamp, is an important part of your car's safety system.

What fuses control the dashboard? ›

The instrument cluster fuse manages the dashboard gauge of a vehicle. It uses electricity from the car battery to power various electronic components of the dashboard such as the different warning lights, gauges, and alarm systems. They include but are not limited to the following: Speedometer.

The start fuse likely feeds power to the terminal 30 pin of the start relay (the relay closes this contact to the starter solenoid and causes the engine to crank). Power comes from the battery, goes to the start fuse, then is sent to the starter solenoid when the relay closes.

Turn Signals Don't Work

This is the most common symptom of a faulty turn signal relay. Once the relay is broken, the lights won't turn on with the switch. On some vehicles, the hazard lights also rely on the turn signal relay, so those lights might also cease to function.

Turn signals only work when the ignition is on; hazard lights work whether the ignition is on or not. The two systems have separate power supplies, so they have separate fuses. You may have a blown fuse. When I turn my right blinker on, why do my hazard lights come on?

In most cases, the main fuse box can be located under the dashboard on the driver's side. This is usually where all of the fuses that control major electrical components are stored. There may also be additional fuse boxes located in other areas such as under the hood or in the trunk.

Locating a Blown Fuse

Consult your owner's manual for the exact location of each. In most cases, a diagram that shows you the position and the name of each fuse can be found inside the fuse box. This will help you locate the fuse that is related to the vehicle component that has failed.

Flexi Says: A fuse in a circuit diagram is typically represented by a rectangle or a squiggly line. The rectangle is more common in American diagrams, while the squiggly line is more common in European diagrams.

Locating your fuse box

You must know where your fuse box is located, in case you need to turn the power off in the event of an emergency. Fuse boxes are commonly found in utility rooms, porches or under-the-stairs cupboards. You may also have one in your hallway or garage.
