I found some good pictures in the interactive parts catalog here for a preview of what you might find:

Under the dash is always a trauma to get to but that's where it is!
there appears to be a front "cover" to get better access if going to the motor but I might first want to check at the the controls as there appears to be several plugs and those may have dropped off, etc.?
If you can access the plugs and find the one set with the wires going to the blower, you should show short with different resistance on each blower setting between wires if good.
I think you will find there is one main wire and then each speed setting will have a separate wire going to the blower area. At the blower there is likely to be a resister pack
built sticking into the airflow. This is a set of wire coils and each setting puts more or less of the coils inline to change the amount of resistance to the blower current.
These have a habit of wire coil breaking and opening the circuit to the motor.
Maybe remove the kick panel for access or go in behind?
Click these for better view!
Example of what to find? May be a different shape, etc. !

If you get a look at the coils, one may be obvious as broken and if it is in the main path ALL speeds are gone! Replace pack!
But it might also be at the controls, so a different place to figure how to get to it!
WHOOPS! I see I marked the wrong screws if it gets down to remove the motor! Go for the ones on the motor, not the ones I marked! Go for the better way, not what I showed!
