Heater air flow help
Replacing my heater core. My car has always had a pretty poor airflow in the heat position. Blows fine through the upper vents but hardly feel any air down below in heat. While I've got it apart for the core is there anything I can check or do to help this? This is my 88 with AC.

The HVAC system uses vacuum actuated doors to direct air. It's possible one of these doors isn't moving all the way or the actuator isn't fully operational.

Might be something like that. Even with the blower on high it doesn't sound like it's really pushing air like it should.
