Why does my Fuse for the radiator fan keep blowing?

Why does my Fuse for the radiator fan keep blowing?

BUT, if there is a short circuit before the fan, it will blow the fuse. Check the wiring is not chaffed or worn between fuse box and fan, or switch to fan. Unplug the radiator fan, replace the fuse and see if it blows again. If not, then its likely the radiator fan is shorted. Use an ohm meter and see what the resistance is.

Why does the fuse keep blowing on my Ford F150?

The most common cause of the problem you are having is a defective A/C clutch relay. Which is why the fuse keeps blowing.

Why does my cigarette lighter fuse keep blowing?

If the fuse always blows without even plugging anything in, and you have verified that there isn’t a foreign object inside the socket, then there is a problem somewhere else in the circuit. In order to totally rule out a problem with the socket itself, you can remove it see if the fuse blows.

Why does the fuse blow on the pink stripe?

Thank you for asking your question on JustAnswer. There is a short to ground, which is causing the fuse #11 to blow on the PK/LB (Pink/LightBlue stripe) wire. Inspect the PK/LB wiring from the relay to to the fuse panel for any signs of damage. Below is the connector view, this is where the PK/LB connect to the interior fuse panel.

Why does the fuse blow when the fan is turned on?

Now let’s say that the fuse blows after the cooling motor is turned on. A simple way to determine if it is a wiring issue or that the blower motor is shorted,is by using an inexpensive test light. Disconnect the fan motor, and find the main power feed wire from the relay to the cooling fan.

What to do if your radiator fan keeps blowing fuses?

Try unplugging both fans and the 30A fuse. Now touch the leads of a 12v incandesent (not led) light (headlight, stop, turn, dome) in place of the fuse. If it goes on you have a short (or something drawing power). If not on, replug in fans one at a time, and both together and retest. Light should not go on or short.

What to do when Your Fuse is blowing?

Because of this, if a fuse is blowing, you again need to narrow down your search. You can do this by finding what is called a splice. This is where a group of wires are connected together and then each wire branches off to its separate components. All of these wires receive current from the same fuse.

Where is the short in a car fuse?

Looking at the circuit described and knowing when the fuse blew will help. If a new fuse is installed and it immediately blows this tells us that the short is somewhere between the fuse box and the relay. If the fuse doesn’t blow until the cooling fan comes on, then the short is somewhere between the relay and the cooling fan.

What causes a fuse to blow in a house?

Fuse panels haven’t been installed in homes for several decades; their technology lacks most of the safety features of modern circuit breakers. Any faulty wiring or connected parts risk a power fault (surge), which trips a circuit (or blows a fuse).

Can a blown fuse be switched back on?

The breakers reset and can be “switched back on”–so there is no need to replace anything. Much of the time, it’s technically inaccurate to refer to a “blown fuse,” so in this article, we’ll offer you some new concepts and vocabulary to describe your various electrical concerns.

What happens to a fuse when it melts?

A true fuse typically consists of a piece of metal, most commonly an encased wire, that actually melts when overheated. This is what stops the fault (aka “short” or “power surge”). The destroyed fuse must then be replaced with a new one.

How often do you get a blown fuse?

Most people probably have experienced a blown fuse at one time or another. Someone always knows what to do when this happens. If you’re a homeowner, that person probably is you. Blown fuses are a common occurrence.

When did I replace the radiator fan on my Mini Cooper?

Both radiator fan & pas cooling fan replaced in July 2017 (this now only August 2018). The independent garage I use diagnosed a faulty fan & fought my cause with BMW to replace it under warranty. BMW charged £120 to do a diagnostic test;they told my garage that the fan wasn’t faulty & their computer showed no wiring defects!

What should I do if my radiator fan is not working?

A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan. The fan itself often uses a big fuse of around 50A, while there might also be a separate small fuse to the fan control module.

Where is the relay on a radiator fan?

The fan relay is often located in the engine bay’s fuse box, but the best way is to check your repair manual to find where it is located. Testing a 4 pin relay is often very straightforward. Remove the relay and give 12 volts to pin 30 and 85. Ground pin 86 and check if there is voltage coming out from pin 87.

Is there a way to test a radiator fan?

You can test the electrical radiator fans by taking a wire from the car battery, unplug the radiator fan connector, and put 12v+ and ground into the connector. This is the fastest and easiest way to test your radiator fans. Because the radiator fan is often drawing so much power, there is often a relay that is powering the coolant fan.

What should I do if my car fuse keeps blowing?

The important thing is to understand what is causing the fuse to keep blowing. The simple fix is often replacing the blown fuse and test the car again. If the fuse does not blow, it might be an easy fix because there was a power surge in the system.

How can you tell when a fuse has been blown?

You might be wondering, then, how to tell if a fuse is blown–an actual fuse, that is. You will see that the fuse has melted, and there might be charring on the panel. A true fuse typically consists of a piece of metal, most commonly an encased wire, that actually melts when overheated. This is what stops the fault (aka “short” or “power surge” ).

Why does my radiator open when the engine is too hot?

You might notice a heavy spring in your radiator cap. The pressure necessary to compress that spring may be different from one vehicle to the next, but the idea is the same. It opens under pressure when the engine gets too hot, so that other weaker points in the system, ie gaskets, do not have to take the extra pressure.

How can I tell if my radiator has blown head gasket?

It is a blown head gasket again, cracked cylinder wall, or cracked cylinder head. A cracked cylinder head will look like a piece of hair laying on the head, it will be right by the valve. You should be able to tell which cylinder it is because it will look cleaner, or still be wet.

Why does my radiator fan on my Saturn not work?

The radiator fan on a Saturn should give you years of trouble-free performance. However, over time, several things can go wrong with it. When the radiator fan does not work, this is a serious problem. The fan helps cool off the radiator, which acts as a heat sink drawing heat away from the engine.

Where is the fuse on a Saturn radiator fan?

Remove the fan fuse under the dash. Open the fuse box by turning the knob on the fuse panel cover counterclockwise and pulling the fuse panel down. Remove the fuse for the fan with the supplied fuse puller (on the underside of the fuse box panel cover). Check to make sure that the fuse has not failed.

What causes a radiator in a car to burst?

They may be electric fans attached directly to the radiator, or you may have one manual fan that is attached to the water pump. There are a few things that can cause a radiator to burst.
