All the first gen Blazer's love to eat the fan control. Pull your heater control out and check the switch. Use a test light to find the hot wire and take a small piece of wire to use as a jumper and test for your three speeds. If it still doesn't run, check the resistor block in the heater box accessible from the engine compartment.
