2005 f150 door locks failure

The Door locks have stopped working on my 2005 F150 Crew Cab. The only thing that works with the power locks is Drivers door Unlock. I've replaced all 4 actuators and that did nothing. Anyone know what the fix is?

Remote keyless is exactly the same as the drivers button. It only unlocks the drivers door. The passenger button does nothing.

Thanks,
Corey

Does it have factory keyless or add on ?   I have seen the lock wires break in the kick panel. Where an add on keyless is hooked to.    There is a pink / YELLOW for lock and pink/green for unlock.    If one of those wires break it will cause the locks not to operate properly

Thanks, it's a factory system.
Seems odd that the unlock still works, but only on the drivers door.
I'll check the wires.

ok if lock and unock only work on the drivers door    the other doors are on a seperate circuit   the other 3 doors are spliced together then go to the body security module pin 3 in connector C3008A its a 16 pin connector at the BSM which is on the left side on the rear wall of the truck behind the rear seat. the easiest way to check the wiring is at the actuators themselves   did you check the wiring before you changed the actuators ??

The output of the BSM is the pink/orange its the same in all 3 doors i would start there

Cool. I'll check it out. The LOCK does NOT work on any doors. Just the UNLOCK on the drivers door.
