2008 4Runner SR5 4.0L V6
When I have my climate control set for feet only the thing pulsates. I mean that it blows the floor and then puffs back out the middle in a rhythm that is not engine speed determinate. I am wondering if the actuator for the switching between the zones is broken, unhooked, etc... Anyone know of a video on this or what pages of the service manual cover this. No idea where to even start a diagnostic.
