I have a 93 New Yorker 5th Ave. The headlights go off and on by themselves. This happens anytime I turn them on. I don't use the automatic headlight function. I pull the switch on and a short while later they start going off and on. I was told it was a bad switch. I replaced it. Problem solved for a short while. Now it's doing it again. I checked the switch and it was burn your finger hot and the plug was melted near one of the contact posts. I'm hoping someone here has experienced the same thing and knows how to solve the problem. Help!
