I recently bought a 1990 RS V8 but been stump with my left turn signal, every time i turn on my car the left turn signal is clicking on and off its pretty annoying driving with that thing going on and off and at night even worse with people thinking i want to make a left all the time lol ..if anybody can help i will appreciated thanks

 

Did you try replacing the control for the turn signal? could be messed up internally.
