Hi - The driver side slider will not unlock. The doors can all be opened and unlocked, but then we close the DS slider and it locks automatically - I have to reach in and turn the manual knob to unlock. Is the manual knob slipping into lock - or is it something eles? Any process of elimination techniques will be great to hear! (or plan answers ? ) Thanks (In another thread, I'll get to the periodic Right Rear clunking we hear.)
