I have a 2003 Mitsubishi Montero Limited that has a tail light mystery that I have been unable to solve. My front headlights work fine and the right tail light works perfectly fine. However, my left tail light works when I am in reverse, press down on the brakes but it does not work when I am driving. I have replaced the bulbs and the fuses look fine and tried to fix it to no avail. I would appreciate it if anyone that has had this issue and fixed it, please advise on what I can do. HELP please and thank you!
