Blower fan switch

My fan switch does not work on the the lower two positions, and I'm worried it's going to quit all together. Living in Minnesota this time of year that would be bad. My truck is a 2014 XL/STX F-150, no fancy climate control just low end dash and controls. Any ideas, these can't have the old school resistor switch can they? Thanks for looking.

My library of schematics for the F150 only goes up to the '13 MY but it's likely the same for the '14.

The '13 does have a simple resistor, much like the older manual systems.

Its not your dash switch its the resistor, be warned there is two different styles. Pull yours to verify if it is the thin one without heat sink or the one with heat sink. They do not interchange.
