Question 2000 Sienna Blower Motor removal

[mmb59]

Sudden loud buzzing from front blower motor. Pulled fan speed resistor, many seeds dropped. Expecting a mouse/chipmunk/nest in my blower wheel. With a quick look, I can't figure out how to pull it. Did pull the glove box and lower dash panel. Does the ECU have to come out of the way? Do I come in from under the hood? Didn't want to go crazy (pun intended) w/o asking around first. Searches didn't help. Thanks in advance.
