I have been looking over the few forums about this problem that I have with my turn signal and tried what they have suggested only to get no results. My left turn signal and bumper light won't blink and won't show up in the dash. The rear left signal does blink however and so does the right signal. I have replaced both bulbs and got nothing. I have checked the ground and it looks fine. I am frustrated and puzzled. If anybody can lend a hint that would be great!
