JDM Rear face vent for 1990-1996 Q45's

OK after seeing this picture here:

I got to thinking that I want that vent too, because I always got people complaining this is supposed to be a luxury car yet it has no rear vents for the rear passengers. Well I don't really car what they think cause I told them to hit the bricks if they don't like it but I like the vent I think it really modernizes the G50 Q45.

So after some research I found out that you don't necessarily have to have the rear passenger A/C, heat and radio controls:



So if I were to cut a small hole in the piece circled in black then lead the pipe to the back of the center console where the vent is would that work?



Is that piece circled in black easily replaceable?

I wonder how the factory ducting works between that splitter piece you have circled and the vent is routed.

Since there is no lever to close the rear vents in the photo you posted, I suspect there must be an additional mix door in their somewhere that's controllable from the rear seat. The rear vents would always (and only) be on if the front dash vents are. Maybe that's how it's supposed to be, though.

The piece you circled sits directly behind the two center vents on the dash (and the clock), so it shouldn't be too hard to get to. You'd just have to pull off the upper center console trim just like you'd do to get to the clock.

I don't see why your idea wouldn't work, though, even if it's not how things were set up from the factory. I am curious as to where you'd route the plumbing for it. Just keep in mind that, as mentioned above, with your setup the rear vents would only (and always) work if the front dash vents are on. If you just run footwell vents, the rear vents won't get any air.

BTW, thanks for posting that picture. It shows exactly the angle I've been trying to find of the plumbing for the steering column vent I need to fix.

There just might be another mix door fo them, but I have no Japanese FSM to go on. But I was think of using (If it fits) a 1990-1993 Q45 passenger vents:



Since you can see in the middle there is a button that allows you to let the air flow thru or not.

I would route it from the center vents down to the radio then under the center console.
