2005 Saturn vue tail lights and dashboard fuse keeps blowing?

Answer 1

Fuses that "Keep Blowing"Fuses were invented, and are designed and intended to do one thing. That is, to "blow" in order to protect the conductors [wires] in a circuit from being damaged from overheating due to "overloading" of that circuit, OR a "short circuit condition."

Your fuses which continue to blow repeatedly indicate either an overload, OR short.

Since overloads occur from adding too many current drawing devices, and unless you've added many extra tail lights to the circuit, this probably is not the cause.

That leaves the short circuit as the culprit in your situation.

Without personally doing "hands-on" troubleshooting of your circuit, NO ONE here can tell you specifically what is causing the short or where to look to find it, but that's what you've got to do to correct the problem.

You need to check every inch of the circuit from the downstream side of the fuse all the way to each of the tail lights and instrument panel lights to look for the short, or shorts, which is a point where a "hot" / energized electrical wire comes into contact with something which is grounded [such as the vehicle's body sheet metal, or a sharp edged metal brace.

An insulated conductor bent tightly around a sharp metal edge can have the insulation so badly chaffed, or cut, that the metal conductor wire will touch the grounded sheet metal creating the short circuit.

Another cause is where a conductor runs between two sheet metal surfaces that are close together, and vibration of the vehicle will cause the insulation to be "pinched" until it parts and metal to metal contact occurs creating a short circuit.

You're just going to have to search for that short, repair the conductor wire if necessary, and/or at least insulate the bare wire with electrician's tape, or heat shrink tape or tubing.
