Door Actuator
 

I need some help please.My door makes this wild rattling sound whenever i lock it, and now i can only use my key to lock the door and still the passenger side door doesn't lock. Can't use my remote key entry system.Is this sign of a power door motor failure or what?And now i can only lock the driver's side door and the other door doesn't lock.so i don't know if i am facing a bad motor or some bad electrical problem.thank you everyone
