did you leave the car to warm up long enough? i thought the same this morning i was sat in the car with the engine running blowers on max and hot but it was just cold air coming out, was the same for about 10-15mins and i got out to check it hadnt frozen, it hadnt and when i got back in it was blowing warm, think it took a while to warm up because it was so cold this morning!

Check the coolant pipes for heat first or leave it not blowing. With the fan blowing through the heater matrix it's quite possible to cool the engine back down in this weather.

There's no relay on the heat side of things, if the fan is blowing then it's either coolant or the air flow pipework and levers.
