I have a 2004 Wrangler that both front turn signals do not work, the front side turn signals work, and the dash arrow works. Front signals also do not work with the Hazard lights. Not sure where to start to fix this.
Could be burnt out bulb, or corroded contacts. I would check out the area and try to clean it up if at all possible. Also make sure that the bulb cover is complete/unbroken so rain and sprinkler water doesn't corrode it. I had that happen to my tail light and had to replace the whole box.
