Why would a fuse make a clicking sound in the passanger side fuse box of a 2003 Chevy Monte Carlo?

Answer 1

A fuse that is not completely inserted can cause a spark. This spark can cause a clicking sound, if enough current is applied. This is probably not the cause, however. A clicking noise near a fuse box is usually one of three things. One cause is a main wire getting close enough to a ground (like the car frame) to spark (called arcing). Another cause is where a fuse inserted in a spot on the fuse panel is not a fuse, but a circuit breaker. A circuit breaker is like a fuse in that it stops wires from overheating. The advantage of a circuit breaker is once it cools, it can be reused. This can take a few seconds, or a few minutes. Some do not automatically reset, but have a button that you can press to reset it. The usual cause is actually not a fuse, but a relay. This is a unit that is inserted in a socket on or near the fuse panel. It will make a click whenever power is applied or removed. When there is a problem with your wiring, this can cause rapid clicking. It will sound more like a buzz. The first step is to make sure all your fuses are properly inserted in their sockets. If the noise doesn't go away, try to determine the exact source of the noise. Going to your mechanic with such information will greatly narrow down the possibilities of what it could be. This translates into a lower bill for you.
