'91 RR Classic is having a mysterious locking issue. When I lock the drivers' door from the outside it reopens instantly. I mean lock-unlock. It acts just like it does if the door is open open and you try it. Same thing. I was able to find two NOS actuators from Europe and that didn't fix the issue. It started out only doing it when it was cold and gradually developed into a full time thing. Everything is just dandy when operated from the passenger side. I've unplugged the drivers' actuator and just lock it manually. Any ideas or suggestions would be appreciated.
