The Door Locks May Cycle Rapidly on Mercedes-Benz ML430

Electrical switches in the door latches can fail, causing the door locks to rapidly actuate up and down multiple times when the locks are activated by either the keyless remote or door lock switch. The affected door latch should be replaced to correct this concern.

drivers side door will not lock, just keeps cycling, what is the repair cost
Rear drivers door lock makes a sound as if the lock is going up and down 3 or 4 times and does not activate the lock to move up or down. Since this problem occurred the car no longer automatically locks when put in drive.
Door locks seem possessed when you push the clicker or on console and doesn't lock the doors anyway. Started when the door panel on driver side starting coming loose. Needing to fix this as am going into the city and would like to be able to lock my doors when there. there are several other things going on with it as well but don't know if I'm suppose to put it all on this one or make additional ones but will find out and be back.. thank you for your willingness to help.
