Your mode door is controlled by vacuum check the vacuum hose on the left side of the intake manifold. these some times fall off leaving your mode door with no vacuum and the default position of the mod door is defrost.

more than likely you will need a new climate control switch unit
Scrap yard or eBay for less than $30 most times.
This is the cheapest, easiest and fastest way to check or repair these.

You have a vacuum leak.Defrost is the default postion(no vacuum).
See if you can locate the small black vacuum line that goes inside the vehicle on the passenger side near the heater core. The trace it back,should see it going to a canister then to the intake manifold.Make sure it is not disconnected or broken somewhere.
