My back window will not go up or down and Since there is no fuse for the power rear on a 2001 Toyota sequoia could problem if motor be locking control window?

It is possible the motor could be locking up the control arm for your rear window. Another potential cause is a failed window regulator, it is responsible for the up and down movement of the window. Check for any obstructions or damage to the regulator and make sure that the motor is securely connected to it. If the problem persist , you may need to replace the motor or the regulator.
