You won't need but the last pic here for reference to the orientation of 3 little screws you're hunting for, to drop the housing with motor and blower.
To get at them you'll remove the kick panel, lower dash conceal and maybe the sill plate. All easy screws. The housing screws are gonna be 5.5, 6 or 7mm head, and you'll find as I have anything from a square block of foam, leaves, twigs, dead mice (lucky if no babies or too much poop). Lysol the whole thing and give motor 2 drops of 3-in-1. There's a little foam donut around the motor cooling tube - usually rotted or gone. Make up a new one to optimize volume/velocity.
