Customer Question

Our 1993 Ford Explorer Limited 4x4 is having an issue with headlights not shutting off even when switch is off AND Auto Lamp switch (on rear view mirror) in OFF position and set all the way to left (lowest time delay). Seems to be a common problem from my research. I've managed to locate the HEADLIGHT AUTO LAMP RELAY and tried a new relay, but headlights still on with headlight switch pushed in (OFF position). Same issue with relay pulled out. Can a headlight switch short out and push current leaving lights on? Only fix is to disconnect battery cable (currently using a quick disconnect terminal).

Hello. I believe the problem is a short in your headlamp switch. They cost around 10.00. I will provide you the means of testing it if you would like. You would need a DVOM to test it.

If you prefer to test it first before replacing it, here is the information to test it. An open circuit will have no continuity.
