Nothing else that springs to mind, it sounds like the control valves are receiving hot coolant if they feel warm, but the hot coolant isn't getting from there to the heater matrix for some reason so either they are stuck closed or there is a fault elsewhere.
Hopefully someone else will come along with some ideas.
