Bump for any answers. I've got a similar problem on my 2002 F250. All four locks suddenly only respond to an unlock command (either from the key fob or door switch). I get a clicking noise from under the dash whenever I open the door or hit either the lock or unlock button on the key fob. I just started reading the long thread on "Power Door Locks Fixed" but can't tell yet if I just have the same old problem everyone seems to have with the actuators. Any advice appreciated.
