The problem is the flasher relay. Drop the fiber board insulation below the streering whell - 2 hard rubber screws and one real screw. Pull off the dashboard below the streering column. Look directly below the air vent into a rectangular hole and see a black box combination flasher attached to more plastic. This is what you want to replace. Insert a screwdriver into the hole and detatch it from the other plastic. Who cares if it breaks off - the attached wires will hold it relatively in position. Pull the flasher toward you and with the flasher in hand remove it from the plug. Get a new one and reverse the process. It took me a long time to do this because I kept trying to figure out how to get to the thing. Should take less that 30 minutes. Good luck.

Chances are it is a loose socket or wire going to the socket it. to check this just turn the signal on and wiggle it this should help you find a loose wire or if the connectoer is bad
