For the past yr I've been having the worst Headlight problems. They seem to go on and off whenever they feel like. I've tried replacing bulbs. I replace the harnest that connect to the bulb. But still the problem still happens. Here the thing. If the right bulb is out. If I just tap the harnest the light comes on. Only to go back off at some point. Same thing for the opposite light. They both just won't stay on. Has anyone had this problem...
