I have a question for K-swappers with a/c.

I have my lines all hooked up but the original d17 connection for the compressor is different then the k-series one. I rewired it but now the a/c stays on constantly. I wanted to know how others got around this problem.

Here's a pic of the connection:
d17,#5


RSX,#5 as well

You are using the k--series compressor right?

 
Rep Power: 301

yes I am. The rsx connection has 1 wire and the d17 one from my harness has 3 wires.

 
Rep Power: 297

uhh... no.. mines has one...and the other 7thgen that i did the swaps in were all 1 wire... i think you got the wrong wire


if you look at your D17 and the K20 compressor there both 1 wire

 
Rep Power: 301

no I actually looked at my old engine and seen the connection on the compressor. 3 Red wires on the connection to the compressor. On the wiring harness end there is a blue/white, blue/brown, and red wire.

I have no idea if this is something different with canadian models.

I was also thinking if the a/c condensor fan comes on when I hit the a/c button then I could tap into that line to turn the compressor on instead of the current hook up I have now.

I'll try and take pics.


Edit: I found this. I'll have to PM him

What wire harness did you use?

 
Rep Power: 297

that funny.. cause i changed comprssors from all years from 01-05 and dx-ex and they were all 1 wire. I think its just a difference between US and canadian

Best way to figure it out. Get a light tester or a multimeter if you have one. turn the car to on but dont start it. Make sure the a/c light in the car is off. Put one end of the tester to the ground on the frame of the car and then touch each wire. If the tester lights up then you dont use that wire.

When you find one that doesnt light up. Go back into the car and turn the a/c button on. Then go back to the engine and touch the same wire. If it lights up then you just found your wire

mine has 1 wire.

 
Rep Power: 279

No i know what your problem is... i just have to remember how i fixed it. My friend had the same proble, with his A3 swap..., 2 of the wires go to the something else... and i think they get looped around. I know this isnt making since, but i had the same problem.

 
Rep Power: 297

funny cause trying to figure out why in a very rare instance that some people have a 3 wire??

because the compressor only needs a power signal... to turn the clutch on and off. Well at least the 1 wire comressors do

as long as he finds that one wire that turns power on and off when he pushes the button he will be fine

What are the 3 wire colors.. i can tell you what i what i did..

ac is for pussies

 
Rep Power: 279

You calling me a *****? Ill play with your k24 any day!

 
Rep Power: 301

one wire is solid red, one is blue with a white stripe, the last one is blue with a brown stripe. See I did what you suggested, I hooked up one wire at a time and the only way the a/c worked was when the blue/white wire was grounded and the one of the other two (red or blue/brown) OR both red & blue/brown were hooked up.

It works but the a/c doesn't turn off. Doesn't matter if the a/c button is on or off.

bring it on *****... lol

i'll be waiting here, just gimmie a few days advance notice..

 
Rep Power: 279

well i know this may or may not help.. But this is how it goes

 
Rep Power: 279

Ide suggest right clicking on it and viewing the image location

 
Rep Power: 301

n/m.....I'll check it out

damn, I need a d17 one to compare.

So what I'm getting is I have to wire the blue/white to the blower motor relay, the blue/red to the a/c compressor, and the red to the ACC in the ECM....

Where is the ECM?

 
Rep Power: 297

have you tried connecting the blue/red wire to the a/c and try turning it on?

 
Rep Power: 279

well yeah in a nut shell... i havent been able to get a hold of my friend. whom we did. but he had the same problem and i seriosly cant remember, but i remember that diagram

 
Rep Power: 301

yeah I did, the a/c won't come on unless the blue/white is grounded.

 
Rep Power: 291

I suppose if all else fails you could wire up an aftermarket switch to power it on and off?

Sorry this is off topic but I am going to be hooking up my AC in the next little while. Which combination of AC Lines did you end up using that worked well? Or were custom ones needed?

 
Rep Power: 301

custom ones for me. the ep3 lines work if you have the ep3 engine. the p/s pump gets in the way on the rsx engine.

 
Rep Power: 297

actually you can still use the ep3 with the rsx engine.. you have to slightly bend the metal part of it that comes in front of the motor about 1/4 - 1/2 inch to the right and it clears perfect

Anyone with the helms manual for the civic coupes want to copy this diagram for me?

 
Rep Power: 297

i think that is the coupe diagram.. if you look at the compressor clutch.. only one wire is going to it.. thats how most of our cars here in the states are.. just one wire runs the compressor

 
Rep Power: 279

Basically that pick is how its supposed to look i got a coupe.. ill douple check for you.

 
Rep Power: 301

yeah I checked the Honda Electronic Service Manual that I got off of here a while ago and it doesn't have the heating/cooling section. I just wanted to double check.

Thanks Xproductionz and TransformedBG for the help.

i can't wait till i get ac again in a month

screwed around with this some more with no success.

I found out some new info. The red wire comes from the A/C pressure switch. So on the a/c pressure switch a blue wire goes in like the diagram except a red wire comes out and on the old d17 compressor it would attach to the thermal conductor.

The blue and white would also connect directly to the thermal conductor, while the blue/red goes directly to the field coil.

I'm kinda stumped. Anytime the wiring is wrong my condensor fan comes on never shutting off and my engine idle will hang high around 1800rpms.
