This is a pretty common complaint and is almost certainly due to a failed heater fan resistor.  This is a stepped resistor with taps that set the different speeds on your blower and if any part of it goes bad, the whole thing doesn't work any more and the highest speed is the only one that bypasses this part. These are often mounted on the fire wall but may not be exposed so you really need a service manual (Haynes or Chilton will do) to locate it in your car.

Heat/ac fan only blows on high


Check the heater control switch,,,,,and the number of wires at the heater motor....Some motors have more than one winding...in which case there will be three or more wires going into motor..there can be burnout in those windings and will require a new motor....check the plug which attaches to the motor....can be bad connection...or at the switch.....but if there is only two wires....then the heater switch uses resistors to slow down the different speeds...and direct connection for high speed....and the problem is definitely the switch...

Check the blower motor under the dash.(on right side put a 12v lead directly to the connection and if it works, the problem may be in the switch relay or resistor pack. (i've also heard of debris holding the fan from moving so if there is power there and motor does not run, remove & check first before buying a new unit.)

Heater relay


First, turn on the fan motor to high, and then tap the bottom of the motor. The brushes stick to the armature, and tapping the motor will release them. Second, check for voltage at the connector for the motor. It should be 3 VDC at position 1, 6 VDC at position 2, 9 VDC at position 3, and 12 VDC at the highest position. No voltage at 1/2 & 3 = replace the heater resistor, located in the air box between the fan & the heater core. No voltage at all? Replace the fan switch.
