I have a NON-A/C car. And the thread is about an A/C car right..? Might be different, true.. But i replaced only the heater radiator (core), not the blower motor, that's true, sorry; for the blower motor I'm not sure, you might need to remove the fender for that..
Sorry for the confusion!
The thread I linked to does contain a lot of pics though, I always like that before I start...
