air vent routing

'96 OBW

 

Seems like most (all?) Japanese cars have the same air vent scheme,

 

---> vent -> vent/floor -> floor -> floor/defrost -> defrost

 

Maybe not always in that order, but always those options. I've never had a dash apart far enough to see how all the plumbing is put together, but I always assumed that these combinations were determined by how the plumbing was routed rather then some arbitrary choice by some engineer in times of yore with the Japanese's strong sense of tradition keeping it alive.

 

What I would really like is a Vent/Defrost option. I like having air blowing over me while I'm driving, I always have. It must be the motorcycle rider in me or something. Man do I miss wind wings, wish they would bring those back.

 

Anyway, if the vent controls are electronically operated (they are right?) would it be possible to switch some wires around and get some different combinations or is like a Y pipe where one route is closed as another opens?

 

Whatcha think?

i just finished changing the heater core in my 96 legacy wagon, the air starts from the passengers side comes out of the blower through the A/C condenser and into a large black plastic box that contains the heater core, there is one cannon plug (brown/9 wire) on the drivers side of the box that controls a actuator that drives small levers in a rotary patern for there corrisponding doors, foot door, vent door, def door. the arms are all linked to one motor, and as certain settings are picked it rotates the arms driving doors open and closed together. I do not think you can mess with the order they operate in. You could however disconect the vent door arm and keep it open all the time, maybe??

 

If you take a flashlight and basically stuff your head in the footwell by the gas pedal and look up towards the center vents you can see the actuaor and the arms. turn the blower on , and reach around and push the buttons and you can watch the arms /actuator rotate, like a crazy clock.

 

Hope this is some help.

Great, thanks Ian for the description! I'll check it out and see if I can't figure something out.

Actually that is the most effecient system for tight packaging of the HVAC system.

 

I figured it was for a reason

 

Lots of luck as there is not a lot of room back there

 

Originally, I wasn't considering actually altering anything back there, I was just hoping to swap some wires so that when I pressed the floor/defrost button, I got vent/defrost instead.

 

i guess opening a window would be out of the question

Ah yes, I almost edited the post to address that

 

Absolutely not, and I have both driver's and passenger's open whenever possible. I'm mostly talking about when it rains. When I had my little toyota pickup, I kept the windows open even in the rain since I didn't care much for the interior which was made out of vinyl and not prone to mold cultivation. But with the 'roo it's a different story. Non only do I not wish to grow mold, but with the windows and door locks being electrically activated, there's even more reason not to let water run down the door panels.
