2 things, one being the thermostat that controls engine temperature, what does the temp. gage read? Next being a plugged heater core, some times you can flush them out. And make sure there is no air in the cooling system.


Beside the thermostat or heater core, it could be an inoperable heater control valve (the valve on the heater hose near the firewall). It is integrated into one of the heater hoses and has a wire connected to it.
