Help me figure out whats wrong with my car!

My brake lights are not working all of a sudden. They work when you turn the headlights on, so I know that the problem does not lie with the actual tail light. I keep blowing fuses labeled under 'brake switch'. I'll replace the fuse, press the brake, the lights come on for a split second, the the fuse pops. I replaced the brake switch, its still blowing fuses. What else could be the problem?

The problem is in between the steering wheel and driver seat.

so you turn the parking light's on and its all good but as soon as you hit the brake it pops a fuse???

check the bulbs..

Well, the bulbs were fine, and its all 3 bulbs on my jeep grand cherokee. The 3rd brake, and the 2 standard ones.

Its scary driving with no brake lights!

I was real confident it was the brake switch, I mean it's the brake switch that is blowing the fuses in the fuse box! But I guess I was wrong //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

there's a short in the electrical... check the spot in the back ( 5th door) rubber boot that protects the wires.. ive seen some dry rot and short out in some older cars door jambs ( spechialy the drivers side..)

when you press the brake switch it completes the circuit witch is +. anything grounded in the circuit will cause a fuse to blow..

Ok, well I'll check the tail light connections, see if anything in there looks bad. If not, I'll be back asking more questions. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Yay, I figured out the problem. My driver's side tail light was causing the short. I unplugged the harness going to that, and everything is working perfect on the other tails. So I guess I just need a new tail light. Thanks for the help!
