How do you figure out why the heater and blower work but the ac and defroster do not?
The HVAC doors that control the airflow are activated by small vacuum motors. The system is designed to fail safe; this means that the system will fail in full defrost mode. So, knowing this and the fact that you have heater but no A/C or defrost you should assume the system has a failed control head (the part that you select functions with with button or lever). Or the doors are stuck due to an warped duct system (usually high heat related).

Why does the ac blower slow down when the car in ceases speed?
Assuming you mean "increases" in speed, as you accelerate the engine the HVAC (Heating Ventilation Air Conditioning) system is loosing its vacuum supply to function properly. Normally the system depends on a vacuum reservoir to maintain operation. This happens when the vacuum supply from the engine is leaking because of damaged/cracked/pinched vacuum lines. Inspect all the vacuum lines associated with the HVAC system.
