Make sure your coolant level is full and both heater hoses at the firewall are warm when the engine is warm. If only one hose is warm you could have a plugged heater core. If both hoses are warm the coolant flow is OK. The problem then may be a faulty temperature door accuator.

so you dont think it is the blower then.

Perhaps I misunderstood your question. Is the problem that no air is blowing at all? If cold air will blow but no warm air the the fault is not with the blower. If there is no air at all blowing then yes, you could have a faulty blower motor.
