I have a 1990 Toyota Corolla and it did the same exact thing as yours and eventually only high speed would work and further investigation revealed the fan switch in the heater control assembly as the culprit. The contact points in the switch had all burned up except for the high setting so I went to the dealer and got a new one and no complaints yet.

Jvrsshurricane is right, but more often the resistor is the culprit. High speed = no resistance, low speed = most resistance
