What is with you people ghetto rigging your A/C???

If you have it installed properly, with the proper parts in the vehicle, with the proper methods used and the correct wiring, you will have NO PROBLEMS whatsoever with your A/C!

It's when you people Cut Corners, Do shade-tree mechanic work, and not want to spend the money to do it right that you have problems.

I'm sick and tired of hearing these scenarios:

"my car ac wouldn't work, so i manually ran a switch to click it on and now its not blowing super cold"

"the car wouldnt idle right with a/c on so its normal for you to bump the idle up a little bit"

ASK yourself this.

When you bought a silvia or 180sx off the lot in japan, did the car salesmen tell you that ??? Seriously folks, start doing some freaking homework. Google. 240SX.org Freshalloy.

I will gladly help you all, but jesus christ, If i don't see anyone making an effort, i will be the FIRST to laugh at your ignorance.

 

Mine works fine now. A belt and a fuse later after a proper compressor alignment by Martin it works fine. Thanks for cold air, Martin!

And Matt, I work a minimum of 45 hours a week (curently 60+) to upgrade my car, so I personally don't have time to browse around for hours for a solution. Just a mere few hours to ask the so called "experts" a few questions. This isn't freshalloy.com or anything, so I don't get the adversity. If I had the time for research, I would know everything and know as much as anyone here. I don't, so we rely on experianced folks to give us insight that we dont have or don't have time to research.

Personally, I am busting my ass working a shitload of hours a week to make my 240 pretty/fast/satisfactory to me. It is a learning process for all, help us out if you have the knowledge or don't say anything.

I appreciate any Nissan help you give me, I really do. But if you came to me with a Ford question like that and I responded like you did, how would you feel? I mean, how hard is it to give someone an honest answer based on your experiance without insulting them with a lecture on how to browse google or yahoo? You're a cool guy Matt, and I respect you, but go beyond yourself and your self rightous attitude.

Bottom line is that if you have superior knowledge, give it and leave it at that. If it is truely superior, people will not say shit and STFU. If it is bunk, people will speak up. Case closed.

I don't know why you go as far as insulting people who are rookies who don't know as much as you do. It isn't helping any of us or making you look any better.

I love ya, Matt, I really do. But back off of the rookies. Remember that we are all rookies in one facet of the automotive community or another. Just as you know everything about all that is 240 Nissan, others know about all that is ________ about ___________. It is all relative. Share it.

Thank you.

 

it's not the rookies that irritate me.

it's the corner cutters.

 

1. If you wire a manual switch to the compressor, the ECU and the IACV will not know to bump up your idle. Either your fuse or relay is bad, or you're tripping the dual pressure switch with your improper charge.

2. R134a, when charged correctly, is cold as shxt. In my car, my keys get condensation on them because the hand vents blow directly on them. Also, my S13 + R134a destroys my WRX AC, which was designed for R134a.

3. Pay the money to get it charged correctly. I'll just go out on a limb and assume that when you put your AC back together, you just dumped a bunch of freon in there. That is exactly the wrong way to do it because you're leaving air in the system. A professional will suck all of the air out first (evacuate the system). Lets add it up. Not very cold = improper charge. Dual pressure switch tripping = inproper charge. ding ding, we have a winner!

 

if you read the beginning of this post i used the proper parts and proper methods... the reason why i had to use other methods after this is because the a\c wouldnt work with the "proper correct methods" from then i tried certain things to try and trouble shoot and make a checklist of problems...

when properly installed , charged and wired the a\c caused the idle to drop, the a\c compressor wouldnt stay on... lines are properly made, and connector to the actual a\c compressor is wired correctly... where did i cut corners...? i am using sr compressor, bracket etc...

"the car wouldnt idle right with a/c on so its normal for you to bump the idle up a little bit"
the reason i asked this is because when i had a\c with the ka .. once the compressor turned on the idle automatically went up on its own to make up for the loss when teh compressor turned on... so maybe i should rephrase the question and ask " why doesnt he idle automatically comeup when the compressor turns on" .. idk rookie here...

as far as the method of charging... we are using actual a\c tools from midas... but maybe ill check with some other shop just to triple check the charge... thanks for the help anyways

 

when i had the a\c wires hooked up factory spec... the idle still didnt raise... so i figured it was a lack of power source maybe?

 

yes those are tech sites as well, and i do frequently ask questions on there... but not knowing some of the member's experience with cars sometimes the information they give is not reliable... where here in our local "tech" forum i have a general idea of the people who know what they are talking about...

if i didnt make any effort on this a\c i would have probably just taken it to a shop and had them do eveyrthing.... but i am the the one doing the work... if i did make any sort of corner cutting it was due to lack of knowledge... resulting in me asking online... if i know that taking the easy \ cheap route to fixing cars isnt %100 proof why would one do it?? in my case i am not a god of air conditioning or anything on the 240sx so if i cut a corner , it was by accident and lack of knowledge... thanks anyway

 

put some gauges on the lines.. see where your pressure is at. I'd say your compressor is low on freon. Try moving the idle up a little as well. Everything should be decently fine after. If you need the pressure / temperature calculation let me know.

 

if you did everythign correctly it would be working.. so maybe you thought you did but you didn't.

go back, recheck everything.

check your wiring. maybe the idle isn't coming up because the wiring wasn't done correctly? If i remember correctly you and shaun did it, and it was the first one you've done.


what cooling method does your car have? if you are running the cluch fan, a secondary electric fan needs to be on when the a/c is runing to keep the condensor cool. otherwise the pressure will get too high and it will cycle off, even if everything was installed correctly. if you have dual electric fans, then make sure that they are on when the a/c is on!

from there, make sure that you did install a new dryer. if you did not, there will be moisture built up in there and that will keep your a/c from becoming an ice box.

lastly, make sure you don't have a leak! a leak will make you ahve all sorts of A/C problems. if everything works perfectly, the iwring is correct, the drier and charge is correct, and your condensor cooling is active, then the only thing i can think that it would be would be the expansion valve. but make sure that everything is right before you go to that diagnosis!

 

thanks a bunch ill quadcheck everything again!
