So, are you able to change the blower speed but the air flow stays the same?
Or does the fan speed stay the same regardless of which setting you select?
If it is not changing the speed of the fan as you increase it on the switch, then it could be due to a faulty blower motor resistor. Many times, the resistor will go bad and will only provide one speed.
The blower motor resistor is located on the fan housing, under the dash on the passenger side.
I have attached diagrams below for your reference.
Let me know of any questions.
