Check the heater hose and heater core could be clogged-up or a problem with the air mix/blend door due to a defective actuator or vacuum.

Yep, I agree with RASMATAZ, aslo, you could have an air bubble inside the core as well, here is a guide that will help you fix the problem as well.

Here is how to bleed the air out of the heater core if flushing it with a garden hose does now work. Check out the images (below). Please let us know what happens.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
