My headlights on my 2001 Ford Explorer are now continuously on while the switch is off and the ignition is off with the keys out. The only way I can shut them off is by pulling the "Parklamps Relay and Main Light Switch" fuse. I unplugged both the main light switch and the automatic light sensor, but it didn't work when I put the fuse back in.
Any recommendations?

Thanks.

I followed all the steps and ran a continuity test between the headlight relay #2 terminal and a ground. I did have continuity between those two points. At this point it looks like I need to replace the wire between the connector that goes into the rear view mirror and the #2 terminal for the headlight relay in the realy module, but what is the easiest way to go about this? Where does the wire run down to from the rear view mirror terminal? How do I get the wire into the connectors if I need to replace it or is there a section of wire harness that I can buy and just replace the whole thing? Thanks for you help.

***As the wiring harness to the autolamp circuit is bundled with other harnesses under the roofliner at whatnot, the easiest to replace a wire is to splice that wire (with a new one) from the rear view mirror, and run a new wire along the roofline to the "pillar" to the relay module. Just follow the same color fro, point A to point B. I can attach a wiring diagram with the post, but it will be way too small for you to see. If you need it, send me an email and I will forward it to you. Make sure you put a link in the email to this topic, so I know it is you.***

Where does the wire run down to from the rear view mirror terminal?

***It is hard to say. Usually all the harnesses are bundled up together under the "A" pillar at the factory, it is almost impossible to know which "route" is used.***

How do I get the wire into the connectors if I need to replace it or is there a section of wire harness that I can buy and just replace the whole thing?

***I highly doubt that Ford will have a wiring harness for this specific circuit. They will have the entire wiring harness for the entire car. Actually, it is not a bad idea if you want to call your local Ford dealership and ask for "Autolamp Circuit Wiring Harness".***

Thanks for all your help. My email address is frederik_ferrell@hotmail. Com. Do you know if the wiring from the sensor goes down the driver's side or passenger's side of the windshield? Thanks again.

It doesn't say. But since the junction box is on the driver side kick panel, I would say it will go through driver side "A" pillar.
