First replace your flasher these are usually not that expensive. If this does not work then check for a short somewhere. As above if you had a bad fuse, the blinkers would not work AT ALL. Most likely is a short somehwere in the wiring. First check your ground for the blinkers as this could have come this. More hance of a ground coming loose that a wire being split underneath the dash. So replace flasher, check the grounds, then go after the "hot" wires. hope this helps.
