hi i have the same problem, i unpluged the p/s and used the fob and it locks but oby have to lock the p/s manually, but plug it back in and it does nothing on the p/s and the drivers side locks and the unlocks, ive tried removing the module from the p/s and pluging it in and trying it with the door shut, still doesnt do anything, but if i put my finger on the p/s cental locking modual and push it down it kicks in the motor and shoots it back up, any idea whats causinig it?
