Hello guys, can someone tell if the door lock actuators/motors are the same front & rear? My C300 is a 2010 Sport. I happen to have a spare door (left side rear) complete with a perfectly working lock actuator. My actual (driver's door) lock actuator is shot! Not good!!! Will the rear door actuator/motor work on the front (driver) door??? I will certainly appreciate your time and help regarding this problem. I tried youtube but couldn't find a video for the W204 door replacement.
Once again, thanks in advance to all who "pit-stop" and shed some light here!!!
