I love my avalanche but it has problems with heating like the blend door just quit working and started smelling antifreeze in cab yesterday, unhooked battery to see if it changes anything , nothing so I'm assuming clogged heater core or blend door , help lol.

If you smell anti-freeze, I'd say you have a leak
I'd flush the heater core and test it for leaks
Yes it could, that leak would show under the hood.
