Hi all

Maybe I've been not looking hard enough or glossed over it but I have spent ages trying to find the answer to my question without any luck.

I'm about to get stuck into the dual zone conversion in my VE SV6 after many months of saving to get the parts

Mattis guide is an excellent and well appreciated guide but I'm stuck with the wiring for the passenger blend motor

What plug and where the heck do I wire the blend motor into ???

I can't seem to find a wiring diagram or mention of it.

Any help would be appreciated as this seems to be the only detail I don't have or can't work out

I know it's been ages but did you work it out? I've just finished and was successful. But you can't follow that other post to the letter, they made big mistakes, especially with the blend doors. I got my hands on a factory pdf workshop manual, and it was essential. Unfortunately without changing the whole air box, you can't have separate blend doors, it will be a fully automatic system, but you can't get separate temperatures. And you need to mount the passenger air blend actuator on backwards, or you'll burn a motor out.
Let me know if you want to yack about it.

So just throwing this out there, and I know this is an old post, but the guide as it is written is correct, and abren73 is wrong.

You do *not* have to change the air box to get proper dual zone. The single and dual zone boxes are exactly the same moulding (I know, I had both side by side) the only differences are the hole for the ambient air aspirator isn’t punched out, and the two blend doors are connected in the middle so they can be driven by a single actuator.

You have to reach in through the air outlets at the top and grab the two blend doors, then wiggle them back and forth in opposite directions until the (fairly thin) connection that joins them in the middle separates. They will then move independently and you can have different temperatures on either side of the car.

I drove my VE for nearly two years after working this out and documenting it for this site, and many, many times had cool air on my side of the car and warm air on a passenger.
