I thought I had a blown fuse, stopped by the local parts store and picked up one of the square fuses. Installed it, it did not fix my problem. Checked all fuses that I could find, no help. Checked for power at the brake light switch, has power to it, but none coming out. Figured this might be the problem, not for sure. One other note, I was towing a buddy in his Ford (ha,ha) several days ago, had my hazzards on they quit working, have been having problems ever since.
