I have a 1990 Vert and the right turn signal wasn't working on my last trip out. On the way home, the left turn signal started flashing on its own. I shut the car off and it was still flashing! The only way to stop it was to disconnect the battery. It started flashing again as soon as the battery was re-connected.

HELP!!!

I haven't had a chance to go through the shop manual schematics yet.
