The easiest way is to have some else do it!! You have to remove the dash to get to the heater core.

Its slightly under the dash on the passenger side. I don't think you have to remove the dash, just the glove box if anything. Just look up under the dash and you'll see the box, just look around and you'll see the blower motor, just follow the box and you should see how things are set up. I'd recommend a repair manual, it will be a big help.
