Hi, I'm having problems with my headlights. They blink as I'm driving. I noticed that they blink more often if I have the heater/ac on. I've had it checked by a Kia dealership and they said that I needed a new alternator. Spent $100 on the new alternator and the lights are doing the same thing! I had it looked at by a mechanic (more $$$) and he checked all the wires and fuses and said that he fixed it, I wasn't 2 miles away from his shop when the lights were blinking again. I have no idea what to do next. I did read a complaint online that a Kia's headlights weren't working at all and the post said that he put in a new Headlight Control Module. I've typed that in on all different websites and no one shows anything like that. I need to know if that would fix the blinking problem before I spend any more money. Please, if anyone knows anything about this problem, let me know. I would deeply appreciate any and all help. I live in a mountainous area and it gets dark at about 3:30 in the afternoon.
