What causes the fuse to blow on the parking light?
What causes the fuse to blow on the parking light?
If there’s a short to ground on the grey wire from the BCM to either the instrument cluster or the heater control, it will blow the parking light fuse! That will cause you to waste a lot of time and money replacing the relay and BCM when those aren’t the problem.
When do you replace the parking light fuse?
The problem arises when the parking light fuse blows and you replace the fuse. As soon as you turn on the parking lights or headlights, the parking light fuse blows again.
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 does the parking light work on a Chevy?
Simple, so the BCM can provide power to the instrument cluster and the heater control to provide illumination at night. The indicator light in the instrument cluster alerts the driver that the headlight parking lights are on and the heater control illuminates so the driver can see the setting on the heater control.

What to do if your parking light is not working?
Use a jumper wire with a fuse in line. Find a parking running light near your battery. Remove light and connect jumper to battery positive and running/parking light wire. If fuse blows you have a short and blown fuse somewhere. See if all your running/parking lights outside come on. Circuit is OK.
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 to do if your fuse box breaks?
This shows that the fuse melted its metal filament to break the circuit. If the fuse box is in a dark place, use a flashlight to locate the blown fuse. Remove the broken fuse and replace it. Using needle-nose pliers or some small tweezers, remove the broken fuse and in its place replace with a new fuse.

How does the BCM work on a parking light?
In a vehicle with a BCM, the multifunction switch doesn’t actually switch power to the parking lights. Instead, the multifunction switch acts as a signal input to the BCM. The BCM provides ground to the control coil circuit of the parking light relay.
What to do if you have a blown fuse?
Keep track of breaker trips. Look and listen for flickering, buzzing, or dimming lights. Look out for frayed or chewed wiring. Search for discoloration, scorching, and smoke. Smell for burning and odd odors. We recommend you use the link above to read NECA’s full list, which includes detailed explanations of these items.
What causes a circuit breaker to blow a fuse?
Any faulty wiring or connected parts risk a power fault (surge), which trips a circuit (or blows a fuse). So, again, the problem is not that the circuit breaker (or fuse) didn’t do its job but rather that there was faulty equipment.
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” ).
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.
