1. Check heater core hose and make sure both are hot when all is running and warmed up.
2. If not heater core is plugged. Remove hose and back flush with garden hose or fill hose with water and use air pressure make sure you don't use to high of air pressure or it will cause damage.
This was my problem. Hope this helps all.
