Answers :

I had the same problem. Take off the radiator cap when the engine is cool, start the car and top it off. I still had liquid in the reservoir, so don't trust that a full reservoir means a full radiator. Two and a half gallons of water later, the heater started working again.
Heater core may be blocked u may have to disconnect and attach a garden hose back and forth at each end to free the blockage if your able or replace the core
