Where do I find and access the blower motor resistor?

What is your question?

The heater blower motor has stopped working. The problem started out as intermittently not working to not working at all now. I removed the motor and put it back in, thinking that the motor fan was being jammed against the housing or maybe a loose connection. It worked for a couple of days then stopped again. Research and talking with a couple of auto wrecker guys and my parts store the general consensus is the blower resistor. So here I am. I have a Hayes manual for the 2000 - 2004 L300 and the description given appears to be incorrect. I tells me to remove the instrument cluster and then remove the right heater vent.(Cluster is on the left so why would anything to the right be accessible?) Anyways,("when all else fails, read the instructions. right?") I removed the instrument cluster and found a solid dash plate with no obvious removal screws/bolts. Searching the internet I've found references to the blower motor resister being on the right side of the vehicle beside/under the glove box. I pulled back the side panel and all I could find was the heater core. Any help will be appreciated.
