Heater , A/C Blower does not turn off

What is your question?

I had my heater on high and when I went to turn the heater off, the "OFF" & "High/Low Blower Control" Settings did not work. When I turned my engine off, the blower continued to blow on high. I pulled out the fuses that mentioned anything about a/c under my steering wheel but it did not turn off the blower. The only way to turn it off is to disconnect the battery. What kind of repair am I look at here, Could this be a blower motor resistor issue? Thanks
