driver's window won't go down - 93 90csq

[Joseph Hollinshead]

For whatever reason, my driver's side window won't go down.  I pulled off the interior panel to do some troubleshooting and checked 1) to see if there were any broken wires at the door jam (none) 2) swapped switches and was able to raise/lower all other doors, so I know it isn't the switch. 3) all contact points are clean - no corrosion (CA car).  

 When I push "up" on the switch, I hear a small clicking noise, however, when I press "down", I hear nothing... which brings me to believe that it has something to do with the motor. Is this a correct assumption? The question is, How should I go about checking the motor? or even removing it. I removed the regulator nuts, but can't get the regulator to come down low enough.  The bentley says that I need to remove the "door component carrier", which looks lengthy and difficult.  Is there anyway to safely remove the motor wo/ doing this? Or is the carrier easier to remove than the bentley shows.

Thanks for any advice,

Joe
