Ok, on my 87 Burb I have no brake lights or hazzards. Everything else works. I replaced the brake light switch, 2 hazzard flashers, bulbs are good. If I hit the brake switch on my trailer brake box the brake lights work. I'm /forums/images/graemlins/confused.gif and not sure what to try next. Any ideas? ***Update*** I looked today and found the hazzards and brake lights are on the same fuse which was blown. I put in a new one and hit the hazzards, they worked for a second and then the fuse blew. Put another fuse in and hit the brakes, poof it blew. Any ideas or should I start looking for a short in the wires?
