a/c problem 2

[Javelin3o4]

okay so i dont get a good rush of air through the a/c vents on the dash, I can feel hot/cold are when the heat selector is changed but it seems that i only feel the air if im driving around 65mph+ if im idling you can barely feel anything comming out of the dash. Also last time i checked my a/c clutch doesnt engage. Changing the fan speed doesnt seem to affect anything. Anyone have an idea? bad blower motor? the fuse is fine.
