A/c blower motor final stage resistor. Very common. Located near firewall on right hand side of transmission tunnel (mounted in the heater/ac box).

Thanks Tuna, it is very difficult to get to and replace?

Not hard at all. I'll take some pics and post them for ya to give you an idea of location and procedure. Stay tuned... :)
