My Truck might be Possessed!

I was walking by my truck while it was parked on the street -- and all the lights (including the headlights) started blinking all by themselves. I got in and it was clicking from the center console (maybe a relay) -- here is the video (click link below)

I had been intermittently getting a 4x4 light blinking and an ABS light -- also sometimes as that was blinking I would lose my turn signals -- after this light show -- I just changed the multifunction switch & the plug to it. I just hope it is not the Devil!

Looks like a first gen in the video. Those have had problems with a leaky windshield that floods the fuse box and the GEM.
If that is the case with your problem you need to have the windshield sealed first.

Thanks! I did look for windshield leaks & spots on my floor under driver's side dash. I also took a mirror (& pictures) of my GEM and I can see no signs of water infiltration. I bought another GEM that matches my Expedition exactly (it's a 2002 EB) -- if the problem returns I will do that job next. BUT if I do that -- does the windshield need to be removed & resealed first -- or can I calk it somehow? Has anyone ever had their headlights and other lights just start blinking all by themselves - with NO key near the truck? By the way -- I do have the keyless entry on the driver's door -- could this cause these issues if water is getting to it?

If the windshield isn't leaking there really isn't a need to reseal it unless you want to be proactive.

Are the blinking lights pulsed randomly or are they pulsed on a regular interval - similar to an alarm sounding the horn?

Thanks for your interest. They pulsed on a regular interval - similar to an alarm sounding the horn.

You can see in the youtube link that there is a loud relay clicking -- the headlights are reflected in the car ahead -- this started when I was no where near the Expedition and when it was locked. Click the link below.

Hit the panic button on the key fob and see if it pulses the same.
I would watch the video but I'm listening to some ol hippy music right now....priorities...

Funny! Yes, it is kind of like this -- except the horn was not honking in the video -- but also I had noticed the horn was muffled when I would hit the button to turn the alarm on -- now that I fixed the multifunction switch the horn is clear and loud with alarm setting button and with panic button. So perhaps you are correct that I hit the panic somehow -- but the horn just wasn't working -- now it all does.... Will drive it and see if the 4x4 and ABS lights ever return. Thanks!
