Ac in 02 tb not working on fan speed 1 or 2

Need help fan control on the ac and heat not working in setting 1 and 2 I changed the control unit in the dash which I was told was the fan control switch but have the same problem

Did you replace the resistor board behind/under the glove box? That's what controls the fan speeds. A search should yield a bunch of posts on this.
