This is likely to be an air lock. Squeeze the hoses either side of the matrix and see if the heater starts working. Watch you coolant level.

It could be a number of things?
If you did have a air lock & low coolant level there is a good chance that your temp gauge would show above normal on a spirited drive. Then that would point to the above. Sometimes the blower will blow luke warm air then cold.

You also need to check the metal rods that attach to the servos motors on the heater matrix unit. They may have come off or your servo is dead. So your heater seeting may be stuck on cold.
