Have you checked the coolant level? And did it have enough anti-freeze in it? Or could the lines to heater core be frozen?

Make sure you check the actual level in the rad not the reservoir. Could be air-locked ,if your fluid level is below your pump you wont get coolant flowing to the heater core.

There should be a bleeder valve on the line somewhere to let air out of the cooling system. If no air on the system try flushing your heater core
