A/C No volume??? on 2001 BMW 330Ci

The fan goes from high to low, however high feels like it should be the low setting as far as air flow is concerned. Blower seems to be fine. Is this an FSU problem? Any suggestions?

its probably the final stage fan resistor my car did the exact same replace it and it should be fine
