Scalifludesi · 05-23-2003, 12:11 AM

No. The JDM unit supplies ground to the AC (BLUE/YEL) wire. Try connecting that wire to the body ground and see if your clutch engages. If it does, something's wrong with the JDM unit provided that you installed the evap temp sensor. You need to short the BLUE/YEL wire with the BLUE/RED wire on the thermostat. About the YELLOW/BLACK wire, I have no idea why its there...mine has only 2 wires.

According to the circuit diagram, the YELLOW/BLACK wire supplies a positive, high-current to the AC clutch and it's nowhere near the thermostat (it goes to the compressor clutch relay).

ECHprelude · 05-23-2003, 01:11 AM

well i read up in the helms and it says this is how it goes...
a blue/blk wire goes to ac switch and outputs a blue/red which goes to thermostat. that turns to blue/yel which goes to control panel. all of this carries a small current. so that blue/yel does have current. i checked it again and yes it does have a small amount of current. im now checking to see if the switch is bad. says something about a green wire, but i dont remember seeing a gren wire...ill update in the morning. all nighter for me. its my birthday!!!

Forbidden · 05-23-2003, 04:29 AM

My thermostat only had 2 wires also I don't know where your 3rd wire comes from.

ECHprelude · 05-23-2003, 11:54 PM

i dunno either, maybe cause mine was a s model or mabye cause it was automatic. who knows. either way i didnt do ish with it. connected the other two together, found out my ac button doesnt work on my unit and also the heater valve solinoid only works at 18 and since my unit works backwards i winded up wiring those two wires to a switch which goes to the ground. guess what. ac kicks in

yay for me. my ac fan was broken though so when it started turning it was loose and melted spinning against the radiator. so i took that out. now i just need to find my ac leak and i will have a working climate control. no auto feature yet till i find a way to reverse the air mix motor. i just need some sorta ac for now. need to probably get yet another unit too. one with a working ac button so i can rid the switch. but i now have a working unit that blows cool. yay for me. forbidden, you need to get your ass in gear. need you to figure out the air mix motor. reversing the wires didnt work.

Scalifludesi · 05-24-2003, 08:23 AM

Eureka!!!!!! I found the way to install the air mix motor and FULLY open/close the valve (before, mine would only open/close halfway) without even reversing the wires!!!! It's actually so simple that I was laughing so bad after I made it work

So it's official now- 100% functional. So without further adieu here's how I did it:

You need to use the cable from your old UDSM control and install it to the JDM air mix motor. If you notice closely on the pics, you can see that the air mix motor is at the coldest position and that the cable is fully pulled. You also need something to hold the outer sleeve of the cable so that it doesn't move when the motor pushes the inner cable:

With that setup, you can virtually mount the motor anywhere! Your only limitation is the length of the cable, but if you want a longer cable you can also use the cable from your bicycle's brake cable

I wish I have a video recording of this in action:

Detailed write up with pics on how to install a 100% functional climate control will soon be up after I'm done with my finals. So stay tuned

L-U-R-C-H · 05-24-2003, 09:05 AM

So we don't have to bend that metal bracket at all?

Also, I think I am missing something from my unit. It didn't come with the wiring harness that plugs into the Power Transister. I was thinking maybe this is already on our USDM cars? Or do I need to get that harness from somewhere?

Scalifludesi · 05-24-2003, 09:10 AM

no bending/modifications at all. Just install the cable on the air mix motor correctly and....viola!!!

L-U-R-C-H · 05-24-2003, 09:13 AM

Sweet ass! Now, can you tell me if I need to get that harness to the Power Transister or not?

Mine came with it but I think it's similar to the ones already in our cars.

Forbidden · 05-24-2003, 11:04 AM

Scalifludesi: nice! I thought about doing that way too at first. I guess that's what I'll do when I get a JDM air mix motor, pretty soon I hope. Problem is I now have a new toy that I need to put some money on too...

Zimmlude · 05-24-2003, 01:26 PM

That is what I first thought about doing when I was considering getting the unit. It make so much sense because there is NO modification to the air-mix linkages. Good to see you got it working

ECHprelude · 05-24-2003, 04:59 PM

good idea.

MidNKight-lude · 05-25-2003, 02:08 PM

damn you justin arghgg boo you sux haha ok now get me a jdm unit and do mine

ECHprelude · 05-25-2003, 08:52 PM

complete unit on ebay right now. everything needed for swap. last i checked it was at $100

95VTEX · 06-27-2003, 03:42 PM

Ok I have been quiet for a months on this topic and now I talk. haha Ok I have a problem trying to find the air mix motor. Has anyone used the Acura Cl motor? If so please let me know. Also Do I honestly pull my dash? I don't mind if I have to some ghetto action.

At the moment my system:

Turns on. illumination
Turns off
Memory works.
Dosn't blow air yet. I just use the old fan selector.
Defrosts.
Vent control works.
Recirculates (? it pulsates?)on off on off on off.....etc.

Just need my flippin MOTOR, relay,and trasistor. If anyone has any extra parts please sell them to me.

Scalifludesi · 06-28-2003, 01:12 PM

95VTEX:

Sup man! You're the one with the half-functioning CC at LFW right? I'm the guy that's supposed to email you that picture of the air mix motor. Unfortunately I lost your email address. But anyways it looks like you finally joined PO.com and obviously you saw the pictures I posted here. BTW maybe (again maybe...) I can get a hold of some hard-to-find parts for the CC conversion like air mix motor and transistor ($95 brand new off Acura dealership for transistor alone

). Just give me a few weeks.

95VTEX · 06-28-2003, 03:59 PM

yeah its me. I just paid my 6 bux finally haha. Well if you could get your hands on those parts that would be cool. Also I have quiet a few wreaking yards in my area. So I will check them out for a few parts. Transistor and relay correct? Or can I use a radio shack realy? thanks for your help in advance.

Zimmlude · 06-28-2003, 08:05 PM

Hey,

To let you guys know I was able to get a source for ALL my parts in one place. The guys is really cool and gave me a good deal

His e-mail is volkrays@dslextreme.com and is an e-bay seller under the name volk-rays

HTH,

95VTEX · 07-01-2003, 02:59 PM

Ok guys

*did the Acura cl power transistor WOrk? is 25 bux a good price?
*did the fog light relay work in the blower motor setup?
*and what is a good price for a air mix motor?

ECHprelude · 07-01-2003, 07:27 PM

yes yes and $20 is a good price. i got transistor from junkyard for cheaper. i found some other acuras that has a transistor too that would probably work too. any 12v relay will work. there are tons of them everywhere on hondas, so just go find a junkyard and cut one out with the harness. same with transistor. make sure you get harness with it so its easier to do. the air mix motor you can also get from a guy called boris on ebay. his email is somewhere in this thread if you look.

95VTEX · 07-02-2003, 02:24 PM

I need a JDM evap temp sensor? what is this for?

I can get a Air mix motor for 60$ shipped ?? good or bad?
I'm geting my foglight relay relay in a week.
Picking my power transistor from the acura junk yard today 25$

Anyone have any other resourse I can try to find parts on?
at the moment I only have one volkrays@dslextreme.com he is the one selling the motor to me if I agree to the 60 bux.

Suggestions

Also WHO IS DONE ??? the last I read people were having probs

prelude styl · 07-02-2003, 02:33 PM

you have to put it in your evaporator, it tells the AC when to turn off from it getting too cold inside the evap. The US one has one, it's a little metal cylinder with a very small copper wire coming from it leading into the evap, but it doesn't work the same way the JDM one does.. you actually have to short out that system to use the JDM one.

Zimmlude · 07-03-2003, 02:21 AM

Hey guys,

About the evap sensor. I have the sensor and am planning on pulling the dash out to do the install. I was wondering if there is any way I wouold be able to avoid getting the A/C drained/recharged to install the sensor. I was thinking I might be able to get the bottom cover off the evap and work the sensor into place.

What do you think?

ECHprelude · 07-03-2003, 02:56 AM

i put my sensor exactly where it is on the jdm unit. not on the evaporator but on the heater box thingy. i never drained my ac line. dont see why you would have too. of course, my ac line was empty to start with

but no, dont think you will have too. so wish i woulda taken pics during my install. i just copied everything from the jdm unit on to mine best i could.

if anyone needs a relay or transistor, i found a set in my garage left over. dont have the harness for the transitor but i do for the relay. i have an old air mix motor too, but its fried :P . i think $65 is WAY too much to pay for that motor. ill give anyone who needs the transistor or relay it for free, just pay shipping.

prelude styl · 07-03-2003, 09:33 AM

ECH, I'll take ur transistor. I had blown mine, and 'fixed' it by regrounding the blown fuse within the transistor, but a new one would be best.

You got a PM bro.

Forbidden · 07-03-2003, 03:01 PM

Zimmlude: I don't see how you could do that...

ECH: you put you evap sensor on the heater box? where did you put it exactly? on the JDM it's on the evap box where the A/C thermostat is, except on the other side because of the RHD.

also I emailed boris but haven't got a response yet... so I guess I'll have to find another source for my JDM air mix motor...

Zimmlude · 07-03-2003, 03:19 PM

Hey ECH, I'll take the relay off your hands for you

Let me know how much shipping would be and I can paypal you the money.

Forbidden, Have you tried volk-rays at the e-mail above? He works at a yard that imports front clips and sells the engines. He should be able to get everything that would be needed, even the vacuum controled heater valve.

I am going to try and get the sensor into the evap without draining the system as it is pretty expensive to do, we'll see.

Thanks,

wutangben · 07-03-2003, 05:28 PM

ahh! i could have used those parts! anyone have anything else extra laying arround? i need the relay, the transistor, and the air mix motor

my girlfriends gonna kill me if i dont install this soon!

Forbidden · 07-04-2003, 01:36 PM

Zimmlude: Yeah I sent an email to him yesterday, I'm waiting for an answer...

95VTEX · 07-04-2003, 02:49 PM

Forbidden: He is out of town for the weekend. I was talking to him to get parts. what all do you need?

Zimmlude: Is there a way to install the evap sensor without draining the system? I don't know how you are going to do that. So please let us know. Mad props if you can find a way

ECHprelude Does your system work with the sensor in the heater box?

Zimmlude · 07-05-2003, 02:04 AM

I guess we'll see. I have been studying the Helms and I think I might be able to. If nothing else I could secure it to a straightened wire hanger and feed that through the hole that the USDM sensor goes through. Might be kinda ghetto but save some $$$.

I will let you all know.

wutangben · 07-05-2003, 12:28 PM

I'll trade anyone a climate control unit for the air mix motor, transistor, and relay. (i have an extra CC unit).

95VTEX · 07-05-2003, 03:21 PM

lets figure this out guys it is dahm hot outside. haha. and black leather isn't so forgiving. black on black.... outch.

prelude styl · 07-05-2003, 03:28 PM

..you guys know that the CC can be fully functional w/o installing the evap temp sensor, right? If you're waiting to instal the evap temp sensor in order to finish your CC... you're waiting for no reason. It works as long as it's wired in.

Now, I'm not saying don't instal it... I'm just saying for 95vtex that you can use your CC as long as everything is hooked up, the sensor can just sit somewhere and the CC will work.

ECHprelude · 07-06-2003, 12:26 PM

yea, what he said. ^^^^ it will work anywhere.
i emailed you guys back about my extra parts.
sorry, im not on po.com much anymore.

ECHprelude · 07-07-2003, 08:58 AM

omg, all 3 of you guys paid me at like the same time. hahahahaha
im going to junkyard today and i will try and find more parts for everybody so i dont have to chose who gets what. what all did you guys need? one said transistor and one said relay and one said everything. is this what u guys need?

prelude styl · 07-07-2003, 10:38 AM

just the transistor bro.

Zimmlude · 07-07-2003, 10:52 AM

I just need the relay.

yohan420 · 07-07-2003, 12:51 PM

What people actually have this working and fully functional, where are all the writeups located? I know there's gotta be more than one ... I didnt read too much into detail about the cable/temp. motor... is this a mod where you hook the motor up to the cable and it changes the heat/cooling instead of having to ghetto a bracket onto the airbox?

prelude styl · 07-07-2003, 12:54 PM

I posted a thread a few days ago with people who have them fully functional, including myself.

prelude styl · 07-07-2003, 12:57 PM

Here's the link for you:
Actual Head count of Functional JDM CC's??

95VTEX · 07-07-2003, 02:52 PM

I need the transistor w/harness, evaperator sensor and your blown motor.

wutangben · 07-07-2003, 09:45 PM

i need the transistor, relay, and air mix motor (like i stated above). hopefully i have a good place in line

ECHprelude · 07-08-2003, 11:56 AM

ok, which 3 paid me? you guys didnt give me your PO name.
i got another relay from the yard yesterday, found another transsitor but what a ***** it will be to get. pass. door is smashed in. ill get it today though. so...what i ahve is a transistor, 2 relays, and a blown air mix motor. i dont know where the evap sensor is on the acura, but i'll look for it. just let me know who paid and for what and ill get what i have shipped out. glad i can help u guys

junkyards here rock!

yohan420 · 07-08-2003, 01:12 PM

O/T but can you get me a powered antenna ? I got one of them rubber stubby ones thats like 10" high and sucks for reception

prelude styl · 07-08-2003, 01:16 PM

I paid you bro. I'm Ryu.

95VTEX · 07-08-2003, 10:05 PM

I paid . I'm Jeremy. I payed a lil extra. haha. Thanks. And the evap sensor should be in the evaporator. The junk yards in my area suck. THANKS FOR THE HELP.

yea, no problem. got a couple there im pretty sure. ill let you know how much they want for it. PM me though, this topic is for the CC unit install. hehe

ok, i tried to get another transistor, that thing is hard to get at on acuras. its like under the airbag on top of the blower. ill keep trying. if you guys could please PM me with what you paid for with your address ill get it shipped out tommorrow or next day. also let me know if you need anything else. im glad to help.

Bertico78 · 08-30-2003, 01:07 PM

I'm following you guys on all this info.....and beginning to understand most of it!! Glad i joined this site

In a couple of weeks i expect to have my JDM CC completely installed.....thanks!!!

95VTEX · 08-31-2003, 07:36 AM

PARTS PLEASE!!!!!!!!!
ok after a bunch of mixups with ordering parts still need,

POWER TRANSISTOR !!!!
AC EVAP SENSOR !!!!!
WORKING MOTOR !!!!

If anyone can help with any of these parts I would be forever thankfull. The wreaking yards in my area are hella dumb. They will only sell the whole AC system. not individual sensors and stuff. So anyone please help
