What good is the 2 in air duct for the driver?

That 2 air duct from the heater box goes through the box to left that has the trailer/ parking brake valves. The plumbing to the valves completely squashes the air duct. I am in the middle of replacing the parking brake valve. My thoughts is while its now accessable to remove the duct. use the box it was in as the air duct. There are three holes on the drivets side. 1-for the flex hose that goes to driver door area. 2-for the CITS lead. 3- a oval hole way down in front for wire harness. As all the holes are on drivers side leave them as is. They would become the air outlet to drivers feet.

Has anyone else dealt with this?

Suggestion?

Maybe yours was just routed poorly? Mine makes it through there without getting squished really.
Mt trailer brk valve plumbing just mashes the duct flat. I can't see anyway to change that. The duct is not threaded through the hoses. It takes a 90 turn right at the top, at the heater box side. This is were it smashed flat. I thought I could put something ridged in the duct, but cant get anything I have through the slot behind outlet panel. As I wanted to finish up the duct is gone and the parking brake valve installed.

Now that I have been in there twice, its not hard to get back in there. I was thinking a smaller more ridged hose.

Wow, I haven't checked mine, but with it like that it might as well not be there. Seems that wouldn't be the original routing.

Maybe an abs, or pvc 90, then to the hose?

Yes, I was hoping someone out there would know what its supposed be like. I agree this is worthless. There was NO airflow at all. IDK. Thinking about it. Access is real tight. Maybe rerouting a hose a completely different way??
