1999 Chrysler Concorde Blower motor runs on high even with

The blower motor on the heat and A/C system runs on high speed only even with the heat and A/C system (Automatic Temp Control) turned off. The only way I can turn the blower motor off is to remove the 30 amp fuse. Everyone tells me the resistor is the problem, but I can't understand how the blower motor is getting power if the system is turned off. Help!

Blown Away.
