when my head lights are off both blinkers work fine...
but when I turn on my head lights my right break light is always on.
Which makes my right blinker not work.
I think its a ground issue... any Ideas?

Hi Shelly your right it might be a ground or the wires are backwords going into the bulb,also check to see that there no bad places on the wires where they can ground out together,good luck, shorts are lots of fun. Hope this helps

it is most likely a short to ground, fallow the wire and test it with a multi meter or a test light

does it have the right bulb in it? it sounds like you have the wrong bulb in it. Compare it to the side that works or switch them and see if the problem goes to the other side. Like I said I bet the wrong bulb is the probelm. Good luck
