My passenger door lock doesn't lock with the fob or with the door lock switch. It doesn't even move, so I have to physically lock and unlock the door each time. I tried searching but could not find anything. What could it be that needs replacing?

 

IM having exact the same problem man..... been searching all over the forum for answers but no luck

 

...have you found out what's wrong?

 

Probably a bad door lock actuator. My bro's needs a new one in his G35 also.

 

it should be the door lock actuator! Anybody know how hard the install is? I removing the glass difficult?
