Many HVAC systems operate with vacuum supplied from the engine. If the vacuum supply is cut off the system goes into default position which is floor and defrost. Look under the hood for a small vacuum line from the engine leading into the firewall that is damaged, cracked, pinched or disconnected.

Most of the ones that I have seen have dirty condensor coils. That's the coil you see from the outside. They get dirty on the inside of the air conditioner where the fan blows air through it.
