Power door lock issue on 2004 Ford Expedition

[jkloster]

When I press the power door unlock button located on the door, the doors all lock. This occurs when I press the unlock button on either the drivers side or the passenger side. The lock button doesn't do anything, but when I press the unlock button it locks the doors. The key fob works fine. It will lock and unlock the doors. The problem only occurs with the power door lock button located on the doors. This is on a 2004 Ford Expedition.

Does the keypad still unlock the driver's door ? If not, it kind of points to a problem with the vehicle security module ( located above the fusebox...).
