After recently doing some audio work in the vehicle drilled new holes for aftermarket speakers and installed with screws, ran wiring for a sub-woofer amplifier, and ran RCA's to the aftermarket head unit installed previously we started having electrical problems with the car. At first, the car would start, idle for a moment, and then shut off. I assumed this was the security system, until shortly thereafter, I noticed that fuses 7, 14, and 19 were blown. Upon inserting new fuses into slots 14 and 19, they popped instantly, telling me there is a short somewhere. At this point, the car does not attempt to start at all, and most of the interior lights are not functional. Interestingly, when I hit the window lock button on the driver's door, the instrument panel lights would come on, although, this has since ceased to occur.
Extra information:
I have since replaced the aftermarket head unit with the factory head unit and removed all wiring related to the aftermarket unit. fuses still pop on contact.
I have opened up the driver's side door panel to make sure I did not hit any wires when drilling holes and screws for the speaker there, but the wires in the door do not run anywhere near the speaker holes I drilled. Did not check passenger door, assuming it is the same.
I have since unplugged all sub amplifier wiring, to no avail and at this point have completely undone all the audio work that I have touched on this car, but the problem persists.
I doubt if I can scan codes with fuses blowing constantly. I noticed some crossover between the fuses that are blowing, and one piece that resides in both circuits is the BCM. Is it possible that I have fried the BCM somehow to the extent that it now creates a short in the system?
