Question Power Window Problem Drivers Door

I have had a problem for the last month on my 1997 F250 king cab 4x4 Lariat, I can be driving along and the drivers window goes down all by itself and I have always been able to just put back up and carry on, but two days ago it did its routine down two three times and I just kept putting it back up and after the 4th time back up it now won't go down. I have tested and done the following:
1. Test switch function all good
2. Test relay all good
3. Check the 4 wires on the button that go to the gem, checked each with an ohm meter all good
4. Had Gem out and no signs of water at all actually just a little bit of dust
5. took truck to dealer so they could test gem (when i was there it worked fine (murphys law) on the way to dealer window went down 25 times in 35 KM
6. dealer checked wires in door and into harness all good no signs of any damage
7.disconnected grey wire which activates the all the way down relay via the gem just to see if this was the culprit wire. no luck
8. drove truck 1/2 way home without the pushbuttons hooked into door-- no window down problem but could here the gem clicking ? When it was clicking pulled over to plug in push buttons and sure enough down the drivers window went ?
9. Put the window up after 5-6 times down and now it won't go down again ?

I am so frustrated with this !! The ford dealer said the next step would be to go through a 30-40 point test and would be min of 4-5 hours at 90+ an hour. I figured someone here must know the problem ? I have done many searchs and I see it is a semi-common problem. I found in one post where the gem and buttons were replaced but didn't fix problem ended up being a ground ? Just not sure which ground and where ? Any help would be appreciated !

My first step would be to swap switches with the passenger side and see what happens.

You definetly have a short somewhere, some how a power wire is getting power. Can you disassemble the switch and see if the contacts inside are loose or sticking.

I have a little more to add today when you start the truck you can count to 1 and the gem clicks and pulls in the relay that puts the drivers window down, if the window switches are not plugged in on the drivers door it just randomly clicks for 2-4 seconds and is ok after this ? If the window switches are plugged in the drivers window goes down ? It does this same thing every time you turn on the ignition ? If you turn the key back to acc. it doesn't do this ?

That was a half hour ago, and I just was out and the symptoms where not the same but the window would not go down until I drove down the road for few minutes ?

Do you think it may be the Gem ? Very weird stuff going on !

Mine is doing the same thing. Mine works until the truck is started. Then the window goes down by itself and will go back up but wont go back down again.
I checked everything also. Everything is good. Switch is good(I even replaced it. Swapped relays around and no different. I was wondering if it was the GEM also. Mind boggling.
