CHEVY HEATER NOT HOT ENOUGH

2000 Chevrolet Blazer

Heater problem
2000 Chevy Blazer 6 cyl Four Wheel Drive Automatic 109000 miles

I have replaced the thermostat and the heater core and still have problems. Some times it is just mild warm and sometimes no heat at all. How much does a back flush cost?

Are the heater hoses hot when up to temperature? Are there any coolant leaks? Heater core could be restricted or there could be a problem with a blend door not operating correctly.
