Climate control wiring Options

[Cavegod]

Hi all i am curently installing cauto climate control in to a non climate control car so thats climate control out of a 1994 jdm Gen6 Celica st202 and installing it into a 1997 uk Gen6 gt st202.

does anybody know where to get a wiring diagram for the auto climate control system as i can only find one for a Gen5 st182 celica.

heres hoping

Has nobody got a wiring diagram??

[njccmd2002]

check the wiki in the celica club uk, i think there is a how to

[Cavegod]

nope the wiki is no good i am fitting auto climate control not the normal aircon.

as the guy on said in your thread on celica club uk, your properly the first, so umm good luck

[trdproven]

You would be the first known

[Cavegod]

sorted it just need to figure out one wire but the system works without it,

its a green/red wire and i seem to remeber it going to the cor and according to the wiring for my celica it then goes to the diagnostic port so maybe the a/c has fault codes?

[Rusty]

yeah I remember reading something about the climate control has its own OBD, so it flashes lights if something's wrong

I can post up the 95 and 97 USDM versions if you want...there might be some differences with the UK version though.

if you have them that would be great thanks!!

PM me your email, I have the wiring for a ST202, might be on there

[Cavegod]

ok the climate control is fitted and i have just 1 wire to connect, green/red wire no idea what its for and i have no diagrams to help me out either. i can't believe there is no info on the auto system, i have got a diagram for the Gen5 auto systems but nothing for the Gen6 system any help with this one wire will be greatly recieved.

[Cavegod]

if anybody has there car in bits can you check 2 wires for me?

i need to know for sure that the orange wire (bottom left) from the left plug of three (black) on the heater box goes to the blue plug on the right above the centre vents, should hopefully go into a blue connector block with 3 oramge and a few brown wires.

also i need to know where the green/red wire (next to a grey wire) from the bottom row on the centre white plug goes to.

[trdproven]

You complete this successfully, you got yourself a certified sticky if you provide the info.

[Cavegod]

i can't believe that a wiring diagram for climate control don't exist!!

just one wire to connect and know way to find out what it does without another climate control car to look at.

[trdproven]

cave - what is working so far on the CC what is functional and what is that 1 wire do? or what is not working

[Cavegod]

everything works but the wire must do something otherwise it wouldn't have it, i was looking at the wiring for the gen5 climate control and that has a battery wire to the A/C auto amp, also checking the gen6 diagrams on celicatech all the green/red wires are battery lives. i have not connected a battery live to the system but maybe this wire is for battery? only way to find out is if somebody with auto climate checks that the wire has 12v constant with ignition off, but getting somebody to remove a bit of dash trim to do it aint easy.

would you mind posting how you got it to work ?

most of us the in US don't have the parts needed for a modification like this, but it'd be good to hanve for those few who do have the parts/

[Cavegod]

yep parts required if you don't have A/C at all like i didn't

1.A/c compressor & drive belt + pulley if different
2.A/c radiator
3.A/c fan
4.3 relays out of the relay box next to Alternator
5.A/c pipes from engine bay
6.Climate control control box
7.A/c box (behind glovebox)
8.Heater box behind dashboard in the centre
9.all wiring from the control box to the blower relay
10.thermistors A/c rad, Dashboard below steering wheel next to left knee uk and right knee usa
11.Solar senor top of dash

think thats all of it for the most part the wiring should already be in the car for normal A/C check for 2 plugs in passenger footwell 1 behind carpet and 1 above the blower ducting, in the engine bay there should be an unused plug near the ignitor with a blanking plug pushed into it, and 1 near where the compressor goes and 1 next to the top of the radiator near the relay box.

hope this helps.

and can I just say climate control is cool

just set it to the temperature you want and it will keep adjusting itself to keep that temperature.

I dont know why not many people have done this?? (well about from a little work )
