05 Chev Silverado has auto temp control and has always had some warm air on our feet but about 1/2 of what it should be when set full feet mode, the dash and defroster are great. Do you think the actuator is the problem? sounds like the one on the right side controls defrost?Thanks

Check all directional doors to see if they are properly working. If you have weak airflow below and it is leaking into another location, one of the doors isn't fully closing.
