Today when going to school I hit my left turn signal and it starts blinking like mad. The last time I used it was two days ago. The right turn signal works fine. I'm guessing there is probably a short somewhere, but my instrument cluster lights doesn't show anything wrong. Anyone know where I should start looking at?

 

It seems that the culprit is a burnt out lightbult in the left taillamp. There's 3 "yellow" bulbs on the sc taillight. Hopefully that'll fix it.
