This here can be a number of things, first of all if your blower is running in only high speed, i would first try to put in a new final stage blower resistor, its located behind the center console on the drivers side, actually right to the right on the gas pedal, also if you are not getting much air to come through the vents i would also try to replace the micro air filter, which if never changed can be clogged causing air restriction, this is also located behind the center console, easy to get to if the glove box, and lower air duct is removed on the passenger side. try doing those simply task first, if still nothing is working, it could be defected air flap in heater box, or fautly ac control module. good luck
How easy is it to replace head gasket on 1994 firebird lt1 motor
Have the speed sensor replaced.
this one is easy your switch the controls the vents is not working there is a flap the closes the defrost vents so that it goes through the other vents or there is a vacumn line that is controlled by the switch, and its leaking. The vacumn line is usually on the engine side of the firewall. It is a very small plastic tube comming out of the middle of the firewall at the top and it connects to a junction with other vacumn lines. See if any of them are disconnected.
High pressure coolant is blowing out through a small hole in your heater core, it will need to be repaired or replaced. If it is warm out it might be AC refrigerant leaking.
