Have been having an issue with my automatic headlights. For a few months, my headlights would randomly turn off while driving, this would occur for just a few seconds. I assumed it was my battery because it had been dying. About 4 months ago, they just stopped working period; however, only when the headlight switch was in the 'Automatic' position (though my dash lights still come on in the 'Automatic' position, just not the headlights and the headlights work perfectly fine in the 'On' position). I then turned around and replaced both the light sensor in the dash and the headlight switch. Neither replacement has fixed the issue. I spoke with a Ford Dealership today and was told this could also be a sign of a bad GEM module. They want $400 for the part, not to mention they want to flash it to my car. So, in closing, I am wondering the following;

1) Could it be the GEM?
2) Doing some searching on Google, I have found a lot of people stating the GEM does not need to be flashed, but I will need to re-sync my remotes to it. Is this also true?
3) If #3 is true, will it affect the remote entry code on my door?

Thank you for your time and expertise in answering my questions.

It might be your relay if it's your gem module a pro can pick it up on scanner if it's bad. Check items in pic

If it was the relay, wouldn't that prevent the entire thing from working, since that relay covers not only the Autolamps, but also the Multifunction and Headlight switches?

Secondly, in the 2000 model, isn't that fuse soldered onto the fuse box circuit board?

The auto lamp relay is powered up by the headlight switch which in turn goes to the gem module. The fuses are all in central junction box which should be your dash box and fuses should be replaceable not a circuit board. If the gem isn't getting ful power that may be your problem. However as I did say to get it scanned as well to see if your GEM is actually bad.

Sorry, I messed up my reply there. Instead of fuse, I meant to say relay, because I had heard that the Autolamp Relay is soldered into the CJB and would require a replacement of the CJB in order to replace the Autolamp Relay. As for getting it scanned, I am out in the boondocks and the nearest dealership to me wants $300 just to hook it up to scan the GEM so I am trying to do this without involving the dealership.

Any garage with a pro scanner cando this not only a dealer. As far as being soldered into central junction box I have no idea so look and seeif it's removable most of them are.
