2000 Lariat Door Lock Mystery

Still cannot get the door lock to via remote, door switch, etc....here is what they do:

- Both locks are activly energized in the unlock postion...if you push down on the lock "tab" it pops right back out.

- If you depress the lock swith on either door both actuators start clicking repetitively-I have to pull the fuse to stop.

- I can pull the cable off the battery, wait a few, reconnect, and then the door locks will work perfectly with switch, keypad, or remote for a limitied times....hours.

**I notice a higher pitched whinning/humming specifically from the location of the 3 door lock relays behind the dash**

- I will leave the truck locked, come out later and it will be unlocked on it's own with the actuators clicking repeatadly. (Again, I have to pull the fuse)

What I have done:

- Replaced both actuators with OEM Ford units

- Replaced the RAP Module (No change in lock behavior)

-Bought one relay and moved it to each of the 3 door lock relay locations.

I am really at a loss here....I think my next step will be to replace the other two lock relays.....I don't think the humming is right?

Could it be the Gem? Any other ideas? Thanks.
