Yeah, right now i got the light green and the yellow/black controling the relay switching the earth for the fan.

I followed the instruction's and use these http://forums.justcommodores.com.au/988326-post63.html pictures as a guide.

I dont see how wiring the relay any differently will change anything? Would that thing that replaced the fan speed resister have anything to do with it?

I assumed the relay only came in when the fan was on full speed, which is what its doing now. When on 1 or 2 speed 12v is run though the 3rd connecter near the fan thats connected to the 12v of the fan. (thats a guess)

Oh well almost there :) Shouldnt of tryed this while installing a alram, pwr windows and mirrors and central locking, wires everywhere!!!

What sensors where?

G'day
just a quick question, as posted by me a few days ago in another post, VP CLIMATE CONTROL WIRING DIAGRAM, I know which sensor goes on the air cond core in the box , but where is the other two go? one has a probe with 2 retaining screws, the other a flat end, any pics would be handy as i no longer have the origanal heater box.
Thanks Robert

Filled the car up with coolant and gave the climate a proper test, everything works but the 1, 2 speed. But im putting the dash back in cause i can fix that later (need the car)

Also i just remembered, i got a dark green wire that i ran to the engine bay for the ac relay, this wasent in the instructions but i think i looked it up in the manual. Sounds right?

1 sensor is the sun sensor and goes to the top middle part of the dash.
2 is the ambient temp sensor and that goes to the front of the car down by the radiator or inside the front bumper.
3 is the inside sensor and that is at the bottom of the control unit and has the little square tube that slots into it whan fitting the control unit.
4 goes inside the condencer inside the heater box
5 is the water temp sensor ant that clips onto the copper tube.

Bottom line is the climate system is very different to the standard system with the fan going the wrong way. We spen the better part of 2 weeks working the wiring out and it's very much the way the relay is wired. I did this last xmas so I'm a positive on how we did the wires - but felt that I had the point no 25 correct. A few others have done the mod and got the 3 fan speeds working.

So I would go back over the relay wires and see how you go. :thumbsup:

What about the green wire? Is it to switch the relay for the compressor? If not what controls the compressor?

Havent tryed them yet since there's no gas i dissconected the compressor.

Mischa,
I have found my wiring diagram from when I did mine.
For the fan, how did you wire it? Positive to the fan should come from the engine bay. This was an additional wire that I used. Negative to the fan should come from the fan relay. I.E. opposite to what the old wiring was. The fan speed resistor controller should get negative power instead of positive.

The wire that you have left over is that Green or is it Green/Black?

The fan is wired so the relay is switching earth to the fan and the resister, and 12v constant from the batt. The relay is being switch by the yellow/black and green, no idea where the green goes but thats what the instruction said to connect it to. So im stuffed as to what it is.

Well i had 10 wires come from the green adapter, everything else ive read said all it should be is 10. Anyway its only green and its a dark green. What controls the ac relay anyway?

Everything works fine apart from 1, 2 speed and ac relay. Im happy i just got the car 'legaly' drivable :p
