Using the brakes is blowing the stop/dir/hazard 20 amp fuse. Trying to narrow the problem area (and using lots of fuses) the directionals and hazards work fine and activate the lights as they are supposed to. Guessing that the wiring to the rear lights is common to the dir/haz/brakes, does that eliminate the wiring going to the rear as the problem?

I just swapped the stop light switch and it made no difference. Push the brake pedal and the fuse will blow after a few seconds - I do not know if the brake lights are activated when this happens. The problem appeared suddenly, worked fine prior.

I am a fairly lame mechanic but especially crippled with electrical stuff. I have a multimeter and almost know how to use it.
