2001 S80 Driver Side window Stuck
 

The driver side window in in the full down position and won't move. I have the door interior all off and the window will not move up or down manually. How can I get the motor gear uncoupled from the regulator arms so that I can at least manually raise the window.. I believe the motor is locked into position. The the guide slide clips to the regulator arms are on the outside of the window channel and I can see them with a mirror but cant get to them. I'm stuck with what to do the window is stuck in the down position. I have not checked the door button but do not beleive that that is the problem. How would I check the up/down button with the door panel and window switches off the off the door? Which wires are the power up and down to the driver side window from the window button? Thanks for any help..
