I think that there is a way to turn the knob until the hole lines all of the way up. Look in with a flash light. There should be a little hole somewhere in the motor as the knob turns around. You can use a small straw to feel if it will go all of the way through. Like a combination lock. Then you will have to fine adjust from there.
The reason for charging is that we have to take out the sunroof liner. Install the cable, adjust it, and warranty the repair. Also we have many, many, many hours of experience invested in doing these things .
