blower motor location on 2002 Mercury Grand Marquis

I have heat in my car, but the motor is not blowing out the air. I need to check it, but am not sure where it is exactly located.

Located in the engine compartment passenger side firewall looks like a black box with two heater hoses coming out of it, Follow the wires and it will look like a snail about 6 to 8 inchs across.
