So I have a 03 liberty that will blow hot for a few seconds
then blow cold and stays cold.  I can switch the
temputure to cold from hot and it blows hot for a few
seconds then gets cold. Any idea what's going on?

Check your coolant level ASAP. If the proper level of coolant is not present in the system, the heater core will not see full temperature, and air that has contaminated the system will inhibit the flow. Fill and Bleed with your heat on and the vehicle running...and check for leaks (since you lost coolant somewhere)!

Also under the hood there 2 hoses going into your heater core. one goes to and one comes out of core. One going in should be fairly hot one coming out should be warm. If they one coming out is cool, heater core could be blocked.
