There are several reasons why this might occur. If your fluid level is low, your engine will not circulate enough antifreeze to fill your heater core ( which usually leads to your engine overheating, but not always if you are just borderline low), if your heater core is plugged (most common) or if you have a sealed system and there is air in the system which prevents your liquidfrom running through the heater core. The most likely cause is a bad heater core which is bad news because it is hard to access, therefor hard to replace.
