fuses keep blowing???

[blackTA6585]

OK, Not sure whats going on but when ever I turn my lights on a fuse blows. Usually the tail lights fuse, sometimes a different one. It has all the correct fuses in each slot. Just started happening yesterday. I've replaced the fuses several times now and as soon as I turn the headlights switch one turn the fuse blows and the fog lights and parking lights cut off completely. The headlights work fine. The parking lights work fine if the headlights are off. Even when I unlock the car with the button the fuse blows. Anybody have any idea what may be wrong??

There is something shorting out somewhere-there was another thread in here somewhere that the guys body control module was filling up with rain water or something-maybe you have a similar issue. If you are not good with electrical stuff and don't see something obvious you'll need the help of a pro to trace it down.

Pull out the bad fuse and if you have an ohmmeter, then measure the side that is not at 12V (in the fuse holder) to ground. If you have continuity then you have a short to ground - which I'm sure is what is going on. Unplug connectors.....etc.... on that circuit until you have infinit continuity to ground from that fuse point and you will have narrowed it down.
