blower fan extraction instructions

[caprio at flash.net]

I'm looking for the best website/ explanation of the 5k blower motor removal.  I think mine is dead/dying.  Here's the scoop:
 
For a while I have been having a slight burning plastic smell when exiting the car, after driving for about 15 minutes or more.  (can only be smelled from outside of car.  Seems to be coming from passenger side of engine compartment, near the firewall)  I've looked around and never found it, I was starting to assume it's related to my Cat. Conv.  No apparent electrical problems, no blown fuses.
 
The smell has gotten worse lately.  AND, my blower started sounding noisy lately-- a vibration droan like a leaf is stuck in it.  So, I stopped running my blower, and noticed the smell goes away.  It's apparently coming from the fan system.  Now, the blower only operates at a very low speed.  I am suspecting that it's drawing higher current (and has been for a while), and thus heating my fan speed regulator, which is causing the smell (so far this hypothesis is untested, I haven't checked it yet).
 
SO, I'm suspecting I will need to change that fan, and probably the regulator, and I know it's going to be a real PITA.  Where is the best set of instructions for doing this job?
 
Thanks
