HVAC question.

I have a 2011 PPV manual HVAC and no matter what position I set the air to come out, it always blows on the drivers feet. The air does change position like it supposed to but it's like the driver floorboard is "leaking". Besides ripping out the entire hvac box is there anything easier fix?

There are multiple blend doors in your truck's HVAC system, and one or more of them appears to be malfunctioning. Do you have, or have access to, a quality bi-directional scanner? If so, you can individually test each of the system's components, an find the source of your issue.

@swathdiver had a great working knowledge of the HVAC system, and he may be able to provide you with some troubleshooting pointers.

I don't have access to one. Soon. But not yet.

Some OBDII adapters and apps can read BCM codes. My kids can use the same FOSEAL adapter I use with their IPhone and the CarScanner app and read Brake and BCM codes.

The problem you are having is most likely the Mode Actuator but could be the controller or a broken door inside the HVAC box. Get the codes and you'll know.
