2004 Other Toyota Models Rear window

Electrical problem
2004 Other Toyota Models V8 Four Wheel Drive Automatic Sequoa miles

My rear window will not operate either by the switch in on the dash or by using the key. I hear a click when I try with the key but nothing happens. All other windows are working properly. Could this be the motor? If so how would I access the motor or test to make sure it's the motor.

Appreciate you help!
