Power windows, click but don't move
 

I just replaced my drivers door module and the control panel on the drivers door and now I have power seat memory, power mirors, power locks, and drivers and passenger front windows are working perfectly. Praise the LORD!
Now, the back windows aren't working.
When I try to make them go up I hear a definite "ckick" inside the door, but they don't move. I replaced the motors and regulators in both of them a few months ago and they were working fine before this most recent electrical disaster.
Any ideas?
Thanks,
