ML350 2004 door locks (2) makes noise does not lock randomly, others OK.

 

Strange, first just front passenger side was having machine gun door issue, now suddenly that became OK, same instant, problem shifted to rear driver side, goes up and down machine gun noise. 

 

Is this individual door actuator problem? if so, how automatically without doing anything front passenger side became OK on its OWN. Driver side rear actuator was replaced 2 years ago, why did it break again, is the problem somewhere else? common controller? signal issue? 

please let me know i can drop by for a check up or suggest what should I do?
