does the blower run when in the HEATER position?

check the HVAC codes, I believe you push the recirc and AC button at the same time. and it should display the code(s).

may be low on coolant as well. a low coolant level will make you blow cool air because there is not enough warm coolant to properly circulate through the system. and yes, you can have a very low level and still not overheat the engine. especially in the winter.
