Question about 2002 Dodge Stratus
If the fan is in the off position the heat is warm. I turn it up and it almost immediately starts blowing cold air. I have replaced my thermostat and flushed the heater core. There is no liquid in my floor board so I don't believe that it is my heater core. I need help!
See if your library has a Stratus shop manual and check the heating system chapter. You didn't say if the engine was reaching operating temperature or not. If the engine is warm but you are not, I would say the problem is in the heat exchanger somewhere. If your engine is cold, you can't really expect the heater to get warm, now can you. Then you have a different problem to chase.
Lack of water on your floor means your heater core is not leaking. It could still be plugged somewhere. The fact that you get some heat initially, but it turns cold when you turn the fan on, sounds like a lack of adequate warm water to the heater core to me. If the engine is warm, it could be a circulation problem of some sort.

where did you buy your thermostat? if you bought a fail-safe style thermostat it could have been no good before you even put it in. also is your tempeture gauge coming up to operating temp?? if it isnt your thermostat may be stuck in the open position allowing the coolant to circulate freely and not actually warm up. i would also check the lines going into the heater core. if one line is hot and the other line is cold than your heater core is probably in need of a flush or replacement.

Remove both heater hoses from motor. Put your garden hose in one end and tape on securely with the other end pointing in a direction the water flow from it will not hit distributor or other vital electronics. Turn on hose - If water come out of heater core at same rate as you are pumping it in then your heater core is flowing - if not then your core is blocked or plugged. Be mindful - if the core is plugged the water will break the seal of the garden hose and heater hose, spraying everywhere, so turn the water on low to check and be ready to shut off quickly!!

squeeze the hoses to get any air bubbles out and refill coolant as necesary. are you sure you put thermostat in the right way? may be backwards. also may be your sensor.
