Window motor replacement
 

I have a 2000, 4 door Chevy Tracker. I have had problems with the window motors in the past and haven't had any problems replacing them. However,this time it is different.
The rear passengers power window is in the all the way up position. I know the motor is bad because I am getting power thru the switch to the motor and nothing happens. The motor has been replaced by me before and I know how except when the window is in the up position. There are 2 bolts that hold the regulator to the window that need to be removed, but there is no way to get to them when the window is all the way up.
How do I get the window down far enough to get to the 2 bolts? All help would be appreciated.
