AC not cold when idling-but otherwise cold

Have a 2006 trailblazer LS with the regular AC (not the digital or whatever it's called)

It's already pushing 90 some days down here....
So the AC will blow cold enough to freeze me out almost as long as the truck is moving even a little bit. Stopped for any length of time though, and it blows kind of warm-ish. Gets cold again as soon as we start going.

Wondah what's going on?

Both TechII and danielsatur make good points, but I had to lean more toward TechII on this one, sounds typical of a fan clutch problem.

Leave truck in park and rev the motor bet ya it gets colder cause pump is turning faster and the pump is getting weak it happened to the wife's Lexus what helps a little is running the recirculate option cools down 50 degree air instead of 90 degree air
