If I have the headlights off, my left side blinkers work outside and in the dash. The right side blinker on the back works and inside the right side blinker works. But the front right blinker does not work. Is that just going to be a bulb? Also, when the Head lights are on, when you turn the blinkers on, the blinker light will come on, but it won't flash, and the front right still doesn't work. Will that be caused by the flasher?
