Heater Control/AC Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Attached picture of a Heater Control exactly like mine.

I know the Blower Positions (Fan Speed) are as follows:
Furthest Position Up is---Off
Next Position down is ---Low Speed
Middle Position is---Medium Speed
Furthest Down Position is---High Speed

In turning on my AC today it was more like this (below):
Furthest Position Up is---Off
Next Position down is ---Low Speed
Middle Position is---Medium Speed
Furthest Down Position is---Low Speed**

The Heater Control is Brand New as is the AC Compressor, so is it some type
of a relay problem, or would it be more likley the Fan going out?

Thoughts/Suggestions/Comments are always welcome.
