Does the vehicle reach normal operating temp? Are the heater hoses hot. Does the blower motor work?

You may have a partially clogged heater core. You can try removing both heater hoses and pressure flush it with a garden hose.
Make sure the sure the system is topped off with coolant when your finished.
