Why does my starter fuse keep blowing out?
The starter can also cause this to blow. If the starter is failing, especially the starter solenoid, a power surge may be being sent to the fuse and blowing it. You can have your starter bench tested, but they wont test if the starter is powerful enough to actually turn over the engine.
Why are the fuses blowing on my computer?
Inspect your wires carefully; hot parts on the engine can easily burn through the wiring’s insulation and short the wires, and metal edges will cut through the wires and short them out. If you’ve got fuel injection, then you might be experiencing an internal short in the computer itself.
What causes a bad or failing blower motor relay?
Blown fuses. One of the first symptoms of a bad or failing AC blower motor relay is a blown AC blower motor relay circuit fuse. If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current…
What causes a fuse to blow on a blower motor?
If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system.
What happens if you have a bad blower motor?
The blower motor is the component responsible for pushing air through the vents of your vehicle’s heating and air conditioning systems. Without it, the AC system will not be able to circulate any heated or cooled air.
Where is the blower control switch on the dashboard?
The blower control switch on the dashboard controls the circuit flow of the blower motor to adjust the voltage from low, to medium, to medium-high, to high. When on high, the circuit bypasses the blower resistor.
What should I do if my fuse keeps blowing?
If the ignition switch is the problem, the fuse will usually blow as soon as the ignition switch is turned on. The best way to find the problem is to trace the circuits with an ohm meter. Something has to be shorted to ground. Didn’t find what you are looking for? Ask a question
What causes the fuse to blow on an alternator?

What are the causes of ignition fuses blowing?
Some of the common accessories that cause blown fuses are things like the starter, the headlight, an improperly wired ignition coil, or one of the onboard computers that control the fuel injection or timing.
Why does the starter motor fuse keep blowing?
More than likely its being caused by a short-circuit to ground in the wiring in your Cranking Circuit. If it blows the fuse immediately after installing the fuse, its probably a hot-wire. If it blows it the second you try to crank it over, its probably one of the wires between your ignition and the Starter Relay.
Why does my power wire fuse keep blowing?
The common issue with fuses blowing would be because of faulty wiring. The faulty wiring or even the defective wiper motors would often lead to the excessive current flow in a system. What this does is result in a blown fuse each time a new one is installed.
