1998 bmw 740il blower motor where is it

The blower motors on this vehicle lis located underneath the dash. The upper half of the dashboard is removable and entails removing the spedometer cluster. The airbag also needs to be removed to get to some usually white triangular looking nuts that hold the wooden trim above the glovebox. Removal of the front side panels to the left and right of the windsheild is also required. If this helps; the blower motor is located right below the large center vent in the center of the dash.

It is in your dash board and looks like a large hamster wheel.
