Hope this helps.
In both of my cobalts the inside of the harness where the bulb "plugs" in, one of the metal connectors had fallen off. I simply just take the wire on the turn signal and pull it out a tad and slip it in so it can make contact(or you can buy a new one) Also, the turn signal and parking lights/marker lamps or w/e are different filaments, so there are two inside of the bulb. (which makes one stay lit, and the other for turn signal, key fob, or emergency lights!
