Yeah, like Larry A. says, sounds like a classic case of bad grounds. If the
rapid flash is still there after the grounds are repaired, you can usually
turn on the hazard flashers to find the culprit. All four corners will
blink, and the dimmest one is usually the perpetrator. Check the wire to it,
the bulb, the socket, and its ground. My right side flashes fast and the
hazard light trick indicates it's the front right at fault. Too lazy to
figure out what's wrong with it though.
