Most likely the vacuum control switch is shot.
It could be more than one problem.
The first thing I would do is pull the blower and clean out the air-box, plus remove and clean out the kick-panels and cowl area.
Access the heater-core, remove it and clean out there as well.
When you have enough stuff out of the way to see it, have someone move the temperature control back and forth while you watch what the "blend door" is doing.
Make certain that it opens and closes completely, and is not obstructed by a dead mouse or whatever.
After you get all this addressed, then you can proceed with trouble-shooting and repairs.

On the one speed- the resister in the heater box needs to be replaced. When they go bad you get only one speed.
