on defrost and heat settings

For what it's worth here is the fuse location, and an image of the blend doors under the dash. But just to clarify, to be 100% on this, what about the foot/floorboard setting?

In the trunk of all places

But I found another in the engine bay on the drivers side. By the air cleaner on the drivers side.
