First of all you really don't have to remove it. Remove the glove box
instead and you can easily see what you need to see to remove the clip
and spring washer from the drive arm and the 6mm screw from the motor
drive shaft.

If you must remove it there is a staple or two through the duct work at
the blower housing, there are two rubber nubbies susupending the
straight run from a bracket attached to the botttom of the dashboard
cushion. The elbow at the right side face level vent is a snap/force fit
at the vent housing and is a snap/force fit to the straight run. There
may or may not be staples at that connection. In any case the staples
are just to hold the assembly together during manufacture and aren'y
necessary to maintain integrity after reinstallation.
