While power stays out, no heat can be generated, so there is no fire hazard at all then. Sometimes the fuse link will break off behind the cap, either because of faulty manufacture or mishandling. Power window switch? A new fuse may restore power temporarily but, unless the underlying cause of the circuit overload is found and corrected, the fuse wont last and will likely blow again. Loose Electrical Connections. Starter Remains On With the Engine Running. While power is still able to flow through such a connection, heat is sometimes developing there, so that a hot breaker or outlet might be a good clue; the heat is unable to start a fire, with rare exceptions. And, you should probably. But I would bet there is a problem with the element shorting to the side of the heating . When the fuse blows, the windows (motors are on separate 15-A fuses) don't work at all, so at a minimum, it's an inconvenience, and at maximum, could mean driving in very poor weather. Due to the way fuses are engineered, the likelihood that a fuse would become faulty without blowing is pretty slim, but there are rare instances in which a fuse might appear completely fine, even though no current runs through it.
