2003 CL55AMG pass door issue

the issue i'm having is that it wont properly lock the passenger door. when I lock using the key fob, lights flash, i can here all the other locks closing, but the passenger door locking knob doesn't retract into the door, also, the power door "closer " doesn't seem to be working either. wondering if they are related. to further complicate things if then passenger door is open, with the "knob" in the up-position, some times it will lock and only pop back up if I go back in the drivers side and pull the handle. any thoughts ?
