Causes. Faulty wiring or defective wiper motors can cause excessive current flow, resulting in a blown fuse. Defective switches may cause short circuits. … Other electrical components, such as heating and cooling blower motors, power seats, electric fuel pumps or air conditioner can all cause fuses to blow.
First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through. … A mis-wired lamp, for example, can cause a short circuit and blown fuse if it is plugged into an outlet.

If the alternator’s fuse or fusible link is blown, the alternator will not be able to charge the battery. The battery then doesn’t store enough power for starting the car or keeping it running.
Blinking, flickering and dimming lights are the three main signs of an overloaded circuit. Some other warning signs can be blown fuses, tripping circuits, buzzing receptacles and a burning odour.

If the circuit breaker does NOT trip immediately: Chances are you have an overloaded circuit, meaning that the circuit has more electricity flowing through it than it is rated for. … If the circuit breaker trips immediately: The problem is either a short circuit or a bad breaker.
A circuit breaker protects an electrical circuit from damage by automatically shutting off power to the circuit.
