after all these years of having my truck, 5 or so, the last 1.5 of them i have been scratching my head about the above ac problem. just couldnt figure out why it would blow cold for hours on end and all of a sudden stop and i would have to get out and bump the ac clutch to make it kick back in. im almost positive mine is suffering from the air gap problem.

thanks for the info.
