A/C Ductwork Schematic

[drakethib]

Can anyone post or email me a schematic or print of how the a/c system is configured in a 2003 AV.

I have a whistle sound when I switch to recirc and even when I turn the a/c of it feels like there is still air comingthrough the vents.

Thanks

Man I remember reading about a few problems with some 03 ac ductwork...and most had to do with the seal to the firewall and letting in cold air up north in winter months......


Also when you turn of auto AC...the truck allows outside air to enter cabin so as to pressurize and help prevent any CO poisoning...
