Climate Air Controls Conversion!

[Steve_Si]

Ok this may not be all that difficult for those of you who already have push button controls.

I'm still working things out with OD, and I will have more details once I have removed the dash from the F1 (which has standard push buttons)

Here we have the plugs for the standard controls, completely unused in my car

Here we have the wires for the climate controls. To my suprise, completely seperate from the main loom.

More to come very soon!

[Steve_Si]

Here we can see the standard loom comes in across the top, the climate controls loom comes in slightly lower down.

They connect to each other using three plugs.

I always wondered why there were so many spare plugs around the blower unit. Now I know, they are for the standard blower unit. The climate control version must be slightly different.

Here we can see the motor unit that control the temperature, selected on the dial on the climate controls. This does the job of the temp slider on the stanard push button controls

I'll be looking in to the motor that aims the air out of whichever vent you select. Seems to be a difference between the push button and climate control versions. I'll know more when I have the F1 dash off.

[A18A]

awesome :thumbup:

your setup is quite different to mine :guh: might post pics later

[Steve_Si]

After seeing OD's setup, it seems that the 87-89 models have the wiring for climate controls integrated in to the dash loom. 85/86 models like mine have the wiring slapped on to the standard loom as an after-thought.

So at this stage it looks like the folloing parts would be required to convert push button controls to climate controls (without altering existing wiring).

1)Climate control unit
2)Blower unit
3)Motor that controls heater temperature
4)Wiring from 85/86 JDM 3G with climate control

Unconfirmed but possibly necessary parts

1)Motor that changes which vents the air comes out of.
2)Fan/temp sensor in centre console, will check if it works without it.

Optional Parts

1)Outside temp sensor in front bumper
2)Temp sensor (or something) in air box beside blower unit
3)Light sensor on top of instrument panel

[carotman]

Hmmm, I have most of these parts already here.

I'll take a picture of everything I have and we'll be able to compare what's needed to make it work right. That's just awesome! I really want to make those work soon. I'm missing the inside temp sensor tough :(

You're my Hero :D

[A18A]

what year is your controls from carotman?

when i replace my alternator, i can probably help out a bit too :)

i also uploaded a bunch of pics this morning if it will help anyone here (http://s154.photobucket.com/albums/s248/87vigor/)

[HondaBoy]

if its the same as mine, that one that you're not sure about should be to the expansion valve.

[carotman]

Well, I couldn't wait and took pictures of the Climate control parts I have.

Here they are:

Out side temp sensor I guess (2 wires)?

Unknown sensor

Another unknown sensor

The control "brain" ?
http://carotman.no-ip.com:8888/personal_site/tech/climate/controls.jpg

3 motors, dunno which one does what
http://carotman.no-ip.com:8888/personal_site/tech/climate/motors.jpg

I guess this one replaces the resistor in the blower motor

The wiring loom
http://carotman.no-ip.com:8888/personal_site/tech/climate/wiring_loom.jpg

A red connector with 4 wires
http://carotman.no-ip.com:8888/personal_site/tech/climate/red_connector.jpg

A connector with 1 wire on one side and 5 on the other
http://carotman.no-ip.com:8888/personal_site/tech/climate/1wire.jpg

The cut loom. I guess this one goes near the passenger foot
http://carotman.no-ip.com:8888/personal_site/tech/climate/cut_loom.jpg


So.... what can I do with those?

[A18A]

were is this located?
http://carotman.no-ip.com:8888/personal_site/tech/climate/controls.jpg

[carotman]

No idea. I received this in a box with all the other parts. I may even have this already in my car (with the push buttons)

[Steve_Si]

"Another unknown sensor" that is just a relay. It clicks when the fans turn on full, and possibly LO and medium.

"A connector with 1 wire on one side and 5 on the other" That is just where the wiring loom for the climate controls gets it's power from. The other wires should match a plug you already have, and that wire in particular should provide 12 volts to the climate controls and turn them on.

"The control brain" Not sure what that does, everything seems to work without it lol. Might be air con related, as mine doesn't work

"I guess this one replaces the resistor in the blower motor" This is the unit that caused my fans to never work on LO or medium. Yes it goes in the blower, meaning you probably don't need a blower from a climate control car.

I'll take another look when I get home

[carotman]

Hmm, it seems I'll get that thing working soon :D

[Steve_Si]

"Rec Motor" recirculation motor, attaches to the blower unit

"Temp Motor" this replaces the manual heater leaver. You can see it towards the right on picture 4.

Other one must be vent selection control.

The red plug cable goes off towards the engine bay. The pink and blue wires are +5v each, for the sensors. It will work without this, but when it is unplugged the heater motor will move a little.

[Steve_Si]

None of the loom would go near the passenger area on a LHD car. As far as I can tell, you just need to wire those big plugs back up and stick them in the back of the climate controls unit. Hopefully the other plugs match up with plugs in the area around the blower unit. If it doesn't reach that far, then chances are it's from a 87-89 3G and you'll have to extend the cables.

The only wires that don't go to the left side of the car are for the temp motor, vent motor, internal temp sensor and light sensor. You can see some in pic # 2, heading diagonally up and right to the vent motor and up then left then slightly up to the temp motor.

[A18A]

is it possible that the "light" sensor could be a fog sensor or something?

[Steve_Si]

is it possible that the "light" sensor could be a fog sensor or something?

Don't really see how

['89AccordLX(Rus)]

is it possible that the "light" sensor could be a fog sensor or something?

The unit may use a light sensor to adjust LCD display brightness. My BMW does that for the onboard computer display using a light sensor.

[A18A]

oh ok....


so what's this cable for?
http://i154.photobucket.com/albums/s248/87vigor/cable.jpg

i see steves silver 3gee must have had this before

[Steve_Si]

that's just for the vent leaver between the 2 centre vents. I think it just brings fresh air through there

[A18A]

i separated the climate control wires from the dash harness, 1 lot goes all the way down to the fuse box, and the rest of the wires go to the blue plug of the main dash harness, here's the difference in the 2 plugs:

normal:

climate control:

and here:
http://i154.photobucket.com/albums/s248/87vigor/wires-1.jpg
the 2 plugs in red are the ones that go to the controls, the plug in the blue goes down by the fuse box. the cut wires go to the blue plug in the main dash harness, th

[Steve_Si]

Wow that's quite different to mine. None of mine go directly to the fuse box or main loom, it leeches off the standard controls loom instead.

[A18A]

maybe yours was converted to climate control back in japan?

[Steve_Si]

Probably the 87-89 models have an upgraded loom throughout the car. Wires in place for folding mirrors and climate controls.

[carotman]

Well, I'm moving thes thread up so I can finish up the project.

I know I'm missing some parts like the vacuum actuator, the sensor above the dashboard and the little fan in the center console. Anyone has these?

[AccordB20A]

i had no idea this thread existed. i also had no idea the climate control came in two types

[forrest89sei]

And thats why we have 3geez my friend :rockon:

[A18A]

if i ge tthis other car i'm after, then i can tear down my vigor and try again :)

[AccordB20A]

i recon your problem is that ur cars a vigor, the climate control that im TRYING to sell is from a 1988 fixed headlight model and its the same as the climate control in my 1985.



I know I'm missing some parts like the vacuum actuator, the sensor above the dashboard and the little fan in the center console. Anyone has these?


i would but im selling the whole thing complete.

[Steve_Si]

It'll work just fine without the centre console fan thing or the sensor on the dash. Not sure about the vacuum actuator though

[A18A]

i recon your problem is that ur cars a vigor

what do you mean :-|

[A18A]

i can start tearing apart my vigor now for this project now that i got a better car lol yay

[carotman]

Yeah!!

I need help to wire mine :D

[AccordB20A]

okay well to sort this out u gta wait till 3gmodifier recieves the climate control i sold him. he has the whole complete thing and all sensors out of the car and even the heater core boxes and blower so if anyone is gunna get it going it will be him.

[3gmodifier]

hey there. i just wanted to let you know that i had bought the complete digi climate control set up from wohdog. i got it all the other day and layed everything out. i set it all up in the coupe and pluged everything in. but i cant get power. i cant figure out ware it gets its power from. and there is a little brown computer brain controller thing on the bottom of the blower. i have no plug to plug into it. there is also a second half to the harness that goes to the engine bay. there is a big 8 pin plug. my accords have no such plugs. i went back and read this post and i realized that this setup is from a fixed headlight model, so that explains why i cant find the plug. what does this plug do and do i need it to power the system up? and after all of the actuators, and main controller is plugged in i am left with a small 3 pin plug that is next to the controllers plugs, and a couple of small plugs down by the blower. so what i wanted to know is do i need more of the interior dash harness to the fuse box to get the rest of the plugs i am missing. i dont wanna have to cut and splice. and even if i had to i cant because i have no clue what wire needs what. if any one has this setup factory, can you run through the system and mark down what goes ware? i need to know what i am missing. thanks

[3gmodifier]

ok. i got a little bit more info from looking at all of the differant pics on the board. i have a some what better idea now. i am gona do another mock up today and see what i can figure out. i will keep everyone posted but help is still appreciated.

[AccordB20A]

http://imagehost.wohdog.sytes.net/digitalclimatecontrol/ thats my pics and wires

[AccordB20A]

oh and that unknown sensor goes in the AC radiator its a temperature sensor for the air thats coming out of the vents
