    We were out last night & for no apparent reason the headlights started flashing, The marker ligts are not effected or anything else but the headlights. Has anyone had this trouble & if so what fixed it. I have a bad feeling it is the dimmer switch but still hoping something simple.:confused:

    Check the connection from the wire harness at the light(bulb connection) it might be loose or have some corrosion in it

    I checked all the connections & they all looked good & tight with no corrosion. I talked to a guy that thinks the headlight switch may be getting weak & shorting out so I am trying that first. I hope it isn't the dimmer switch in the column.

    It doesn't matter which lights are on. It started on the plow lights so I had him switch to truck ligts & they continued to flash, Low beams & high beams it doesn't matter.

    Found the problem. The plug in that goes to the switch has gotten hot & cracked the plastic which caused 2 terminals to short each other out. I went to Autozone & got a new plug & pigtail & rewired it tonight so now I just need another push to let it get good & warm to make sure it is fixed.

    Didn't catch this thread until now but good to hear you have it sorted out.

    A burned/melted connector at the switch is a common issue. The fact that the connector was available in the aftermarket is a clear indicator if that. :waving:

    I finally called my buddy that is a service manager at a Ford dealership & he said that it sounded like this was the problem as he had replaced a lot of them over the years. I was searching for a headlight switch the other night & remembered seeing the pigtail & thought it was kind of odd but oh well as long as they are fixed. Went out to salt this morning & they are working fine so hopefully that is all there is.:D
