A/C is not blowing any air out unless I drive fast, but still... on 2007 Chevrolet Silverado SS

but still, when I drive fast, I can feel the "Coldness" of the a/c, but nothing is blowing out, I don't believe the fan is working. My truck has about 75k miles on it. What could be wrong, any help would be greatly appreciated, it's getting over 100 degrees out side.

Mine did the same thing I have 79,000 miles.
The Fan Module inside the cab behind the dash needs to be replaced.
