Vehicle is a 2008 GL 320. The problem is the drivers side door lock will not lock or unlock with the remote or from inside the car, no shuddering or sound at all, just nothing. All the other door locks work from door switch and the remote. The car is not the keyless variety. I put in a new door lock actuator ( brand new, not used or rebuilt ) and still NOTHING. Anybody have any thoughts ? I'm pretty frustrated at this point. Thanks guys, Will

 

it may seem simple but it isnt---you need factory or equal diagnostics to determine the fault
