sounds like the knob is broken.

I changed my resistor,nope,same thing. Then I changed relay,nope,same thing. Then I replaced switch for 18 bucks online,worked fine till I hit a bump then you guessed it...same thing. I took control panel out with car running and fan shut off, put it back in and it started blowing again. After inspection of switch wires I found one wire rubbing against metal support bracket, tapped it up real good...problem solved. Hope this helps someone.
