Well, ok, you said it, not me

Ok, now you have to go through the car if you keep blowing fuses. I don't have my manual handy, it's the car and my wife has the car right now, so this is gonna kinda be like a blind person trying to describe and elephant to another blind person. it CAN be done, just gotta bear with me here!


Before we get to diagnosing anything, if you have a different stereo in the car, you need to check out all that wiring. all that stuff is on the same circuit from what i can tell from memory. check all your wiring if you've put a different stereo in there, hell check it even if it has the stock stereo in there, cause someone else might've changed it before you and left wires un-insulated. so check all that wiring, make sure all wires are covered good.

Next, you have to find everything that is on that circuit. is it just the one fuse that keeps blowing or is it multiple fuses? check the fuse panels to make sure you have the proper fuses inserted. seems you have a lot more running on your dome light circuit than i do (sunroof) and it might require larger than a 7.5 amp fuse.

Once you've checked to make sure that you have all the proper rated fuses inserted in the right places, then you have to start checking your wiring. your best bet is to physically trace all the wiring. you said you used the sunroof and then the fuse blew out. let's start there then. go to where your sunroof controls are, open up that panel, check the wiring, make sure it's connected good and there's no bare wiring. then get to the sun roof motor and check the wiring there. you're going to have to do this for every circuit that keeps blowing out fuses. if you have all the proper fuses inserted in the fuse panels, then you've got something on the circuit that is either defective and using too much power or you've got a short in the system somewhere. you could also have a break in a wire somewhere that you can't see because of the insulation. This is where a multimeter comes in handy, as you can hook to either end of the wire, and if there's enough wire exposed, you can wiggle the wire around. if you get an infinate resistance when the wire is moved in different directions, it's a bad wire.

This is gonna take some patience on your part and you're gonna be taking parts of the car apart. you need to check every piece of electrical on the car, it's gonna be time consuming. but here's your 2 choices.....take plenty of time to go through the car and try to find the problem, or you can go ahead and just start replacing parts until you possibly stumble across the problem. it's up to you. i prefer to find the problem and correct it instead of just replacing everything til i find the problem. cheaper that way!


DO NOT, under any circumstances, think you can clear up the problem by just putting a larger fuse in than recommended (like putting a 15 amp fuse in place of a 7.5 amp). you WILL create problems for yourself. hope i've been of some help.

btw, what car are we talking about here? year/model.
