blower only has two speeds high and low

1999, blower fan will only work on high and low, is there a resistor that needs to be replaced like in the Cavaliers? Need suggestions what part has gone bad.

You need to replace the blower motor resistor assembly. On my '93 you can see it under the glove box. Has several wires going into it. Two screws hold it in. Don't know if your's will be in the same place.
