If there is hot water in the heater core,why can’t I get heat out of my vents?

Your blend door is probably not working. How do you know the core is hot?

I agree. If the core is hot the problem is with the blend door, which is what directs air through the core. If the blend door is stuck the air bypasses the heater core and you’ve got no heat.
