There are 2 main reasons when heater don't work and
1. Heater hoses clogged or valve not opening resulting in coolant flow restricted to heater core. Are both inlet and utlet hoses hot to the touch?

2. Faulty air mix venting system, could be cable, linkages or air mix motor. When turning between heater and AC, check if the vents are moving and not stuck.

This sounds like you have low engine coolant or the temperature blend door actuator stopped working but to but sure this video and guide can help us fix it.
