I have a 2008 and the same thing happened to me.... after 3 trips to toyota and around 8 hours of diagnostic they finally figured out it was a failed "fuse block" in the dash.
they tried the fuses, new window motor, and a few other things.
mine was under the extended waranty so it only set me back $100... would have cost over $900 and over $600 for the motor.
hope that helps
