How cold is it where you live? Do you have a full load of anti-freeze in the radiator? If it's low, ya won't get heat.

Make sure the coolant is full. Check to make sure the engine is running at a normal operating temp. Make sure nothing has frozen in the cooling system. Next, start the engine, turn the heater on high, and allow the engine to warm up. Feel both heater core hoses. Both should be hot. If both are hot, check the blend door. If only one gets hot, flush the heater core.
