When I go to turn either side turn signals on, both sides light up. Anyone know what would cause this? Thanks

check you flasher and fuses mine did that now only one of them does that. so its kinda fixed

Also brake switch may be feeding current to the turn signals if wirred incorrectly.

Welcome to the board Chris.

Do both light up on the outside or inside? If outside is it both front and rear?

If the wrong bulb is installed at any location it can cause this problem. They should be 1157 bulbs. It is an easy check so start there.
