On the impala, just below the windshield on the passenger side you'll see the black cowl that covers the lower portion of the windshield. You'll need to turn on the wipers and stop them in the straight up position, then raise the hood. Remove the weatherstrip just below the cowl, as well as the washer fluid lines.
You'll need a flathead screwdriver to remove the 3 fittings holding the cowl down. Once the cowl is removed you'll see the cabin filter tucked under. Then it's as easy as removing, reinstalling and putting the cowl, weatherstrip, and washer lines back in place. Also, it's common on the Impalas for a small peice of weatherstrip underneath the cowl to fall off.
This can cause rainwater to leak into the passenger compartment so be sure to secure it back on the metal lip just above the filter. If it won't stay you may need to use some sort of RTV gasket silicone to secure it. That's about all there is to it....
