    I have air coming out of the floor ducts and the defrost ducts, but nothing out of the dash vents. Any thoughts?

    Check to make sure you vacuum canister is still hooked up. Or you could have a vacuum leak somewhere under the dash like me and need to take the whole dash off to fix it more than likely..

    Just a vaccum line snapped near the canister. They get old and brittle and tend to break.

    Where is the canister you refer to on a fox? Do I access it by taking the dash off?

    No it is on the left side firewall when you are facing the car. Just behind the Trottle body but attached to the firewall. Look for a little black vaccum line.

    Should be a silver color. Or mine is anyway. The tiny black hose will be running through the firewall as well.
