so its the actuator that causes this problem?my rear passenger won't unlock electronically, only manually from the inside.my front passenger side door won't open from the outside.seems similar to the frozen door lock in reverse which is weird becauses its been 90 degrees for a while.anyway the door will lock and unlock fine but just wont open when u use the handle.sounds more like a mechanical then an electrical to me but in a bmw you never know.
