Ok so I've been searching and searching cause I know how people hate putting posts that can be fixed with just a little research but I haven't found anything on this topic. My problem is that my left turn signal is out in my tail light. All other turn signals work fine including the 2 front and my right turn signal in my right tail light. also it isn't because of the bulb because i switched it with the right side to see if it still worked and it did. i have already checked all the fuses and everything is in order. my guess is that there must be something with the wiring. can anyone please help me i have never had problems like this before maybe just a burnt bulb but nothing like this.
