noisey heater fan

I have a 2001 focus zx3 with a noisey heater fan. the fan only makes noise when on low speed any other speed doesn't make any noise. how do I get to the fan? if anyone has advice they can e mail me at [email protected]

is your car under warrenty? best bet is just take it somewhere..i cant give you specfics on how to get to it.. but from what i remember hearing from others.. its a pain in the ass to get to...
