Finally found the elusive grey/black trio of wires. Splice looked solid but I re-did it with solder, heatshrink and electrical tape. Reassembled the door because I had the card off to test the switch and VOILA, drivers side (and all others) are working great now.
Oh and for those who can't get the cover up or find the wires just remember that it does come up, there are no tricks and the wires ARE in there.
For the record, mine were about 1/2 way along the sill, lying on the floor of the vehicle, right under the very bottom of the bundle and had a black splice (not blue tape)
Thanks for the inspiration guys !
