Flasher problem

What happens when u unplug the switch? Does the signal flash on the side the brake light is on?R u sure the right bulb is in that socket? Did u change the flasher? Did u try a different signal light switches suggested by omm? Disconnect the white wire from the signal light switch to see if the brake light goes out. I believe there is a plug behind the drivers kick panel or under the rocker sill plate/carpet. Kim
