STLRS FN's FX4

Have an '11 FX4 with manual air, problem I have is the blower motor speed only works on #3 & #4, 1 and 2 don't work at all. I had the same issue on my '98 F150. Turned out to be the blower motor resistor. Easy fix I was able to do myself.


Has anyone else have/had this problem and if so what was the fix?


Thanks
