This is a bit of a guess, but it might be the multi function switch. It can do some weird stuff when it goes bad.

I agree, I've never seen it make one light go out and then the other but it does make both lows go out and the highs will be fine.

Its the turn signal "stick" that you use daily. My lights have been out for a while now just aint had the time to take it apart and clean/check it. I have heard it is fairly simple to do

ok guys i just found this on here

"here is what a gem module does good luck


The Generic Electronic Module (GEM) is found on Ford vehicles and is basically a Body Control Computer. It controls many of the following functions on most Ford vehicles:

Warning chimes and warning lamps
One-touch down driver’s side window
Daytime Running Lamps
Heated rear window
Windshield washers and wipers
Battery saver
Remote keyless entry
Illuminated entry with remote keyless entry
Interior lighting
Perimeter anti-theft
Four-wheel drive"

what dose any of this have to do with my headlights?

Looks like nothing, all fuses check out ok? Bulbs are ok? I guess try and see if your getting juice to the lights at all. I'm no mechanic but I feel your pain, Good Luck man let us know what you find.

I would check the sockets that plug right into the headlamp bulb itself. These have been known to melt a little around the spade connectors, especally if you use higher wattage bulbs. They are very easy to replace and not to expensive. The ones you get at after market stores tend to be a lot better than OEM.
