Recently on a 4 hour trip with the ac on, it sounded like the unit switched to recirculate/max mode however regardless of the fan speed setting the air was barely coming out of the dash vents when this happened. I did notice when this happened my feet began to cool but there was hardly any air coming out of the dash vents. Turning the ac off for a few minutes and back on seemed to resolve the issue, for a short period of time before it happened again. This is a buick lesabre custom with manual climate control w/o separate passenger control. I know there is more than one actuator under the dash wondering if these symptoms narrow it down to which one it might be?
