I have a 96 dodge neon. Automatic 4 cyl engine. If you need to know that. I have an issue with my rear driver's side turn signal and brake light. I noticed this problem when I flipped the turn signal stick and my dash light for the blinker went nuts. The front blinker works fine. The rear blinker and brake light wont flash. Assuming it was just the bulb I went to the parts store and got a new pack. Changed both lights. Now. Still not working. I have a seperate bulb for the running lights and they are working fine. I swapped the bulb to the other side and it works fine. So, I know its not the bulb that is the issue. What do I try now?
