The most likely cause would be a problem with the vaccuum source. Most vehicles use a vaccuum source from the engine, in order to control the Climate Control mode. The default setting is for the Climate Control is for it to return to the defrost mode when there is no vaccuum. I'll bet that there is a bad vaccuum hose is leaking or has become disconnected.

SOURCE: a/c blows from floor
sounds like two problems. the ticking sound is probably a broken blend door stop. the wet floor is probably a bad heater core, both require dash removal.

Sounds like the blend door actuator which diverts air from defrost,to bi-level,vent etc. It's vacuum driven and when it fails, it's usually an indication of a vacuum leak. To trace the leak, start the car, turn the AC on high and starting at the firewall in front of the passenger's side, trace the vacuum lines backward until a leak is detected. If no leak is detected, it's very likely that the blend door actuator is faulty and needs either repair or replacement. Best of luck.

it might be the heater core, it can become clogged with engine debrie. the heater core is just like a small radiator the just passes anitfreeze in it and air passes throught it, that is how the air warms up
