I am having a constant issue with my headlights mainly on the passenger side. All three lights (high beam, low beam and fog light) on the passenger side are dim. When I disconnect the low beam bulb the the other two bulbs light up fully. When I connect the low beam bulb back there is a humming sound that starts and all passenger side bulbs go dim again. My kia Sorento has had this problem for going on six years now. Usually we could cut the car off and back on and the lights would turn back bright. The past couple of time we have had to change the bulbs. Now nothing seems to help. When changing the bulbs they all stay dim unless I disconnect the low beam bulb which I can't do for safety reasons. And to avoid getting a ticket I have to drive with the passenger side dim. Next step is to try and replace the head light wiring harness or take it to the kia service deapartment.
