I have a 1998 ml 320 i think my door lock acuator on my drivers side front door sounds like a machine gun. I have read that this means the acuator needs to be replaced..my question is if i unplug the drivers door acuator will the other doors work? and will i be able to manually lock and unlock the drivers door with the key? thanks for any info.....

 

Check in the W163 section, should get more help.
