Well, heres what you need to do. First check the coolent level like mentioned and make sure it is full.

Then, drive the car long enough so you know that it HAS to be warm in the engine. Stop, pop the hood and CAREFULLY feel the radiator and the hose going from the thermostat to the radiator. It should be hot. If not I would guess your stat is stuck open or not there.

IF that is OK, check your heater lines, if both are hot, then coolent is going thru the core. If one is and one isnt or neither are, its clogged.
