    Default 2007 Silverado NBS- Air Conditioner wont properly cool

    Good afternoon gents,

    So I was away for 2 month(Military) and had to leave my truck in Florida. Well I get back and the truck of course runs great, however, the a/c is not too happy with me. The a/c is not getting cold. It will slightly cool the air and dry it out however, its not a comfortable cool and definately not cold. My friend drove it two weeks ago and he said the a/c worked fine. However here is where I am at,

    As of today,

    -the freon level is good
    -low/high pressure is good
    -clutch on the compressor is engaging, (only noise is the click of the compressor engaging, no other noises i.e. squeaks)
    -It will cool a little better at highway speeds however it is not cold by anymeans.
    -There is no debris on condenser.

    Any ideas?

    I know this may sound funny, but did you try turning the heat on and then off? I noticed a couple times where my 2010 Silverado has done the same thing, but when I move the temperature dial from one extreme to the other and back again it resolves the issue.

    Good Luck,
