Re: Heater issues
Check inlet and outlet temps of heater core they should be very much the same, hot. If not heater core might be restricted and needs to get back flushed or replaced. If both cold might check the heater valve operation. If not might be the controls and blend doors in the duct work themselves. How and where are you checking coolant flow?

Re: Heater issues
The coolant temperature gauge on the instrument panel should show 190F after the engine is warmed up.
