Check the heater core.

Depending on how old your car is, You may be able to pop your hood and open the bypass valve to the heater core manually. It will be along the firewall with two 1/2 inch rubber tubings right next to each other. Try opening that to max and see if the hot air blows in.

Low on coolant. remove upper radiator hose and fill it from there.
