There is a resistor that controls the fan speed,it is located behind the glove box
on the fan housing.This is most likely the culprit..

 

That's correct. The blower resistor is mounted on top of the blower motor housing, (behind the glove box), with two phillips head screws. About $35 for a replacement.
