It sounds like your blower motor may be bad. I don't know if you know how to check power at your blower motor plug, but you can use a volt/ohm meter or a test light. If you have power (12VDC) , your motor is most likely bad. There is also a resistor block module which has 2 resistors on it. It controls the motor speed basically by restricting the power by directing it thru one of the resistors. The higher the resistance, the slower the motor turns, thus the 3 speeds for the motor. The resistor module is mounted on the blower housing and has 2 screws holding it in with a small plug connected. It is just about straight ahead of the passengers left knee.
You can get used motors from a junk yard pretty cheap.

i've been down here too myself, and discovered that the temp control motor, located in the bottom of the glove box, which you can access by clearing all your stuff in in and opening a small door.
you can adjust it manually, and see if it changes, if yes, the switch can be defective, as well as the motor, the switch is the most likely problem.
but adjust it manually first.
