I've trid the vacuum hose behind the passengers side headlig

but, I'm still getting no vent control on my 2002 Jeep Grand Cherokee. That's until I saw the the main hose running into my intake manifold (at least that's what I think it's called), was totally rotted through! Needles to say, I have to replace it, but I'm not too sure what part number it is... I've included some links to some photos if anyone could help me out, or point me in the right direction.

Thanks,
Mike
