There are a number of possibilities.

First is the coolant getting to normal temperature (middle of the gauge). If not you may have a stuck open thermostat.

If the coolant is getting hot but the heater core isn't there may be an obstruction to flow or perhaps the valve isn't opening. I think it's vacuum controlled. Perhaps a vacuum line is leaking. To verify if there is coolant flow through the heater core check if the inlet and outlet hoses are getting hot.

+1 on the stuck open thermostat.

Try that first....they are only a few bucks.
