I have a 2012 Kia optima ex and recently my fog lights stopped working. High beams and low beams are working just fine. The fog lights would come on with the right turn signal on but would not come on any other time. I read that it could be the switch gone bad and replaced the turn signal stalk. Fog lights are still not working and now they don’t even come on with the right turn signal on. The fog light indicator on the dash does not come on either when they are turned on. Any suggestions on what the problem could be?
