Or maybe I have a whistle in my ducts.  At least I got your attention.
With the air conditioning system season in  full gear I've noticed that I
cannot close off my fresh air ducts enough to stop air flow.  At around 40 mph
the air really starts to whistle.  I removed the instrument cluster and radio
and adjusted the levers so I could get more pressure on the blend doors, but it
made no differencer.  Or very little.  Since I haven't had the luxury of
replacing my front heater core, I was wondering if one of you remember if
there if a foam seal on the blend door.  If you answer is yes, I have more
questions.  Can the foam be replaced withour pulling the whole dash apart.
Does it use a special type gasket material.
Maybe I should put duct tape over the air intake behind the front grill and
pull it off this fall.  I'm just trying to give the a/c a fighting chance at
cooling down this huge box.  Any suggestions are appreciated.
