    There are a number of reasons why only cold air is being blown from your heater unit:-
    1) The coolant system may have an air lock, in which the system may require bleeding.
    2) No thermostat fitted therefore offering no resistance to the coolants flow.
    3) Thermostat stuck in the open position.
    4) Dirty coolant system which may require draining, flushing, back flushing, re-filling and bleeding.
    5) Heater matrix block (as above).
