when I use the turn signal and I finished making my turn. The light goes off but the signal sounds keeps going at a faster rate than normal. It goes on randomly from 2-4 secs. Its really wierd. I know that when one of lights is out the signal just blinks faster but now its only the sound. I can't really isolate it to a particular amount of 'click' but its happening on a regular basis now. Any thought?
