When it is damp outside I have a very loud squealing noise that comes from a belt or a pulley but I cannot locate it or fix it. I have changed the belt but I have also seen other GMC trucks with the same noise, is this a defect

    It could be a frozen/stiff belt tensioner that won't put enough force on the belt for it to grip. Pretty common on GM and Ford.
