Turn signal problem
The right turn signal on 1994 Cadillac DeVille blinks very, very slowly. It will not work at all when the headlights are turned on.
Check the bulb flashing too slow. A standard bulb was probably installed in place of a heavy-duty bulb. Also, Check for loose connections or corrosion at the bulb socket.
The bulb was not replaced, it used to work with the headlights on but gradually got slower and slower until it did not work at all.
