You're reading The heater core heats up, but it won't blow any hot air? We just replaced the heater core and the heater box is nice and warm but only cold air comes out of all the vents. What's wrong with it?

Thanks Mrs. Anonymous. The blend door and it's working fine and both hoses are hot. If we open the blend door, the air gets almost freezing but if we close it, it warms back up to just cold.

Are you sure it's completely closing?
