Whistling or squealing?
No Vile, I'm sure Stewart doesn't have livestock in the cab!

You are correct Irish. It is called an air distribution plenum by many manufacturers.

Cancel it: i didn't have the passenger door closed all the way.
You know how it latches without being completely shut? That's what happened.
i am, however, having problems with the defroster not really working----air isn't coming out of the top of the dash. Also, the fan doesn't seem real powerful when put on highest notch.
i will try the search function as well.

I would look for leaves in your blower motor or air ducts. Also if you turn off some vents, it can cause the others to whistle. At least that's what happens on my Honda. Most of the HVAC on my truck doesn't work, so I'm just guessing there.

Sorry. I should have refreshed the page before answering. It was hours old when I posted.
