One of my door locks is loose, such that the pull knob can just fall down when the door is closed. It is also loose with the key. Basically, it's missing any sort of detent to keep it either locked or unlocked. Otherwise, it works fine. After poking around in there, I noted that the working door has a small spring in the actuator assembly to provide this function. Does anyone have any idea where I could get a replacement spring? I've learned that the junk yards around here don't really have anything before about 1995 at this point. LMC doesn't have anything to do with manual door lock actuation as far as I can tell. Thanks.
