What is wrong if air only blows out of the defrost vents?

In: Mercury Cougar

[Edit]

Answer

Under the hood... There is a small "red" vaccuum tube from the firewall to the bottom of a canister on the passenger side and to a "t-tap" on the block. Mine got melted after a tune-up and I had to cut a small section out and replace it. A friend of mine had his disconnected after servicing at the dealer.

Answer

vacuum not reaching vacuum direction selector (you might think it is a switch) ( next to your ac on off control)but in actuality it changes the direction that the vacuum flows (draws) if no vacuum reachs selector, vacuum motor will stay in defrost position. I found my problem to be vacuum line disconnected under dash.
