2006 odysses rt sliding door stuck open the front cable has slack in it

What is your question?

the right door stopped working in the open position, I have checked the fuses, there is slack in the front of the cable, the slide hinge needs to be replaced I have a new one on order, how do I know if the front cable roller going through the body is bad or the motor, when I hit the door switch I don't hear any sound from the motor,i have the interior panel off the car and the white plastic pulled off to see the motor I saw a video of how to loosen the white tensier clips but im not sure if I should do that or not
