Greetings everyone, my 97 dakota headlamps are having a problem. When I turn them on at night 10 to 15 minutes later they start flickering on and off. This does not affect the fog lamps the fog lamp stay on. I've already replace the bulbs and check the fuses and relays. Someone mentioned that it could possibly be a fusible link. I cannot find this fusible link anywhere. Any help on the matter would be greatly appreciated. Thank you and kind regards.
