Cold air in passenger side footwell

I am trying to figure out where a draft is coming from on my 94ZJ Limited. The passenger side footwell seems to have a draft when I am on the highway, however, I cannot figure out where it is coming from. I tried switching HVAC modes and noticed it seem to get momentarily 'worse' while the HVAC shifts into another position.

Any ideas where to start? I do not want to take the whole dash out, but I am thinking that is my option, haha!

There is a HVAC floor discharge register, controlled by a door, as-shown in this topic. Other than that door-controlled opening, the HVAC box dos not have a mode to dump air into the foot well.

This topic also has more images, like this one showing the other side of that register.

I believe I also have this problem. I notice it at highway speeds especially if there is a crosswind or its windy out. I have to be going pretty fast for this to happen, like above 65 mph which I rarely do. 97zj
