I seen a bunch of posts on this problem for replacing the motor/ gear but, I wanted to know if the sunroof cable that connects to the motor is able to be pulled with hands/ pliers to get the sunfoof to open ?

I have pulled the motor off and cant get it to budge, I have even tried pounding on the front sunroof lip to push back and nogo, is it stuck for good ?
or am I just missing a simple step to free it up. OR do I need to start ripping out the headliner to get to an inner mehcanizim that might be the culprit?

thanks for your suggestions
