Question for you 3kGT people out there

Anyone got decent photos of the back end of the HVAC module that comes in your cars? (The digital one) Im trying to come up with a way to use one for a plan I have...

You want a picture of the whole control unit.

Yes, like the back end of the unit your sig has.

I have a spare unit in the garage, I'll try to remember to get a picture of it for you after my nephews track meet.
There is also another control unit under that one that controls something, I'm not sure exactly what it does.  There are also a couple of sensors in the cabin area.

Im trying to modify one (and its components, I suppose) to work with the 3g eclipse... thought it would prove sort of interesting. Where is its "brain" contained? Onboard? I hope its not on the ECU or something... I dont feel like finding a way to create a standalone component for it.
Thnx in advance for the pics, BTW

I'm not 100% sure how it all works.  It is the "brain" so to speak, as there is a PCB in the unit.  The other unit I believe contains the relays for the fan motor and vent control.  I've never really looked at the schematics to see what all is involved in the auto climate control system. 

So Im going to need to install some sort of motor to close my vents, right?

I hate to speculate, but yeah, I think so.

Tru, I doubt that would even be close to the hardest part... but it should be interesting to work out... I wonder if it would be worth making into a kit. Would its dimensions allow it to fit comfortably into the stock HVAC area in a 3G?

Don't know if it would fit or not, I've never been in a 3g Eclipse.  

Hmmm... would you say that it would be approx. the same size as a standard single DIN stereo head unit?

It's about as wide as a standard DIN opening, but about 1 1/2 times as tall..

Nice nice, a  little bigger than I thought... but since this (seems to be) a new theory... Im sure Ill run into a bunch of issues like that... Wonder how I could find out the pinouts?

I would be willing to bet the pin-outs are in the electrical section of the service manual...


...yes...I have the service manual.

The schematic is about 7 pages long.  If you are really interested in doing this, I'll scan the pages and email them to you.  IMHO, this will be an exercise in futility.

Here is the control unit. 




The relay unit is about 10X4X1.

Thanx. lol, its actually more like an excercise in boredom... at work... Boredom and computer tech go hand in hand... I figure Id take a stab at something new.
