Is it just turn left or just turn right or either when you activate the signal both flash? You may have a common wire connecting both. Do you have a trailer tow package? The wire connector most of the time is the problem. If you can disconnect or remove it from the loop see if that is a fix. If so, there is the issue. If you don't there is a common wire that connects both light wires after the relay. Start with the far passenger side and trace the wires if you can to see if they have any worn spots or the connections are lose and touching the other wire. It also may be in the turn signal switch.
