Brakes problem
1992 Buick Lesabre 6 cyl Front Wheel Drive Automatic 150xxx miles

Ok so I keep blowing brake fuses. I've gone through and checked all the connections to make sure nothing was stuck in them that would blow the fuses. Started chasing wires with no prevail. I have a digital multimeter but I don't know how to go about isolating the issue. The only thing I know is that the brakes and the hazard lamps are all on the same line. The hazards won't blow the fuse. Only happens when I press the brakes. I did replace the Brake switch thinking it would help and it didn't. If you have any advice on where to go from here or steps that could be taken to isolate the shorting wires, it would be GREATLY appreciated.

Take your hazard flasher out and seeif you still blow fuses. Change the flasher, if that doesn't cure it you might have a bad turn signal switch. But if this car has been in a collision recently it may have damged the wires goin gto the back to repair it. If you get a compas and run it along hte wires while power is being applied, it will start to spin when you find a short like a bare or broken wire.
