With difficulty. Tried to remove the one in my 1997 and found that you really do have to remove the entire dash to access it. If you have it out already, try to get your hands on a new heater box, saves the hassle.
The heater blower motor on a 1999 Subaru Impreza is in the engine compartment on the passenger side of the vehicle. It is located on the firewall.
