Anyone have noisy air-con?

[Spectrix]

Does anyone else have this problem with their air-con?Intermitant droning noise.. happens about 80% of the time when the air-con is on.
Splash tells me it's the crap compressors that nissan use and I was wondering how many other pulsars have had the same thing happen.

The car's going in to nissan today for a warrenty jobby :Flipa:
They fit crap components, they can pay for replacements.

:devil: They can have fun trying to fix the squeaky clutch aswell..
this started several months ago, I crawled under the dash and greased the mechinism, no luck.
WD-40 sprayed onto it fixes the problem for about 2 weeks.
Obviously I cant get the grease onto wherever the squeak is coming from. I hope nissan have more luck than I did.

[KOPDISSS]

yep common Pulsar faults, have have both problems too, nissan will fix em for nothing, they did mine, and they will again! next service!!! Argggh!

[Spectrix]

Both probs?

Are they fixing the air con for a 2nd time or the squeaky clutch?

[Booba]

I have a n15s2 and yes i get this noisy aircon problem nissan fixed it at 60k service but it has come noisy again i will get them to fix it 70km service

they told me it was the belt or something. if it happens after then i am going to bitch slap em :thwap:

Booba.

[Spectrix]

A belt.. is that all it is?
I was hoping they'd replace the whole compressor

"yeah hi, its nissan here, aahhh.. we can't find the source of the noise or the squeak, so we're gonna need to keep the car here over the weekend to pull the whole motor out and fit the only spare new motor we have, which is a 3.0 V6 out of the new maxima" :thumbsup: :evilgrin:

[Splash]

i can tell you now, its not the belt that makes that kind of noise. Nissan are just wanking your chain.

[Spectrix]

:mad: No one wanks my chain
If I get the car back and it doesn't have a maxima engine in it, I'm gonna spit chips


um.. I don't even have a chain

[Spectrix]

I have a thread though.. woo hoo

[Spectrix]

:mad: Ok so I go down to Nissan to get my car and they tell me that they've fixed the clutch squeak and :
"The grinding noise that the air conditioner makes is perfectly normal, but we'll fit a new compressor anyway, and you'll need to come back next week to have that done."

So I'm on my way home and the clutch is squeaking in tune to the grinding air conditioner and I'm thinking
"That aircon noise can't be normal, and the clutch is still squeaking, how the F%&% did it take them 6 hours to achieve absolutely nothing at all?"

But that's not all, half way home I come round a nice sweeping left hander and go all wobbley... what could have caused this? How bout 30psi each corner?! Thanks nissan!

[Fahootie]

my sss bluebird has the same grinding aircon noise, so its gotta be nissan-centric.

[Salvo]

so its gotta be nissan-centric.

Sorry Fahootie, for a second there I thought you said "Nissan Cedric" :)

[Snuffy]

hmm.. grinding noise?

i've been getting a grinding noise lately... but only at around 2500 revs...

[cargle]

does anyone have a problem with revs lowering when air- conditioner on?

I own a n14Q2.0ltre and when running/idling with the air-conditioner on occasionally my revs will lower to the point of nearly stalling

[Rex]

yeh my aircon is noisy too. I might have to get that checked out next service. I notice the revs do drop but only a couple of times has it sounded like stalling, never has actually stalled though.

the revs should actually be higher when the air con is on, they're supposed to have a feature that automatically adjusts the idle when it comes on.. might need to get it checked out

[cargle]

yeah the revs do go higher when the air-con is on,

however my air-con like our family commodore's air-con periodically clicks out and then back in again (not sure how to describe it) which is all normal, however when this happens in my car the revs lower and occassionaly get quite low >800, then revs rise again straight away.

I will get it checked out in the next service anyway.

[Splash]

when it clicks in and out, is called cycling..

maybe your compressor is getting old and its putting a fair bit of load on the motor.. do you notice more power loss than usual?

[Snuffy]

hmm.. funny.. the idle revs on my N16 are meant to be ~690.. that's what it says on the sticker under my bonnet.. very rarely goes that low.. probably cos i got my a/c on all the time...

[cargle]

actually now that you metion it, I have noiced it has little less power than usual with the air-con on, I'll make sure I get it all checked out in the next service

[NIXSSS]

And i thought it was normal!!!
i own a N15s2 sss, next service its going in for a check up on that damn noise comming from the air con!!!!
my clutch also feels grindy.. better get em to check it out...
:D

[Chrissso]

I thought that my car was just singing to me!!!:o
Mine's done it from day one. Did't care to much.
Is it damaging?

Hi all,
time to rekindle this thread.

I had my air con gassed today in my N14 SR20 Q.

It ran out of gas on the way up to the Jamboree in october, and i finally got around to regassing it, but its not working too good.

I got my mate at a crash repairer to to the R134A retrofit and top up the gas.

There was absolutey no gas left in the system, so a new reciever dryer was fitted $35 and the new fittings fitted to swap R12 to R134A fittings.

We found three leaks in the system and no blockages.
We had to replace the o-rings on the receiver dryer, compressor and the one on the condenser (near the radiator cap)

We fired the car up and it cooled to 13 degrees out the vents on a 31 degree day in adelaide. cool i thought, but the compressor was making a horrid rattling noise which it wasnt before.

When i am driving, the air con is kinda cool. as soon as i pull up at the lights, the air con shits itself and blows hot air until i start moving again - like 2 kms down the road after the traffic lights. Its giving me the shits and my old silver N14 Q did exactly the same thing. Its like the condensor gets heat soak and the aircon becomes inop.

I thought only one of the thremo fans were kicking in, and when i pulled over to check it, only one was going, but later today i checked it and both fans were going under the bonnet??? I might just brigde the wires on the fans???

What should i look for next guys? perhaps the compressor? considering it is making a horrid rattling noise? My mate has DET'd his SSS so he has a spare compressor off his SSS and another spare off his U12 DET engine he purchased

Any ideas guys? its gunna be 36 here tomorrow!

Cheers
hot and bothered Drew... :confused:

[dominic]

YUP my a/c has started to make that weird grinding noise only when im idling at the lights - otherwise its quiet :)

Hrmmm as for taking it to the local nissan dealer..dont they charge an arm, leg and ear for a service?? i never took mine back to them hehe

[Spectrix]

Well shortly after I made this thread nissan replaced the air con compressor with a new one, which stayed quiet for about 2 months.. but now it's worse than the original.
Also recently I went in complaining about the (still) creaky grindy clutch and asked them to lubricate the throwout bearing, and when they pulled it apart they found it was rooted and had to replace it. Feels beautiful now, what a difference.

Its great that this stuff gets done under warrenty but I'm getting concerned about maintainance costs once it runs out!

[Drew]

well im heading down to the beach in about half an hour. I'll see how the aircon goes in the 36 degree heat today.

it'll prob shit itself i assume.

im assuming the compressor is cactus. hey my N14 is 11 years old now, so prob not too surprising... (mine is a Nov 91 N14, one of the first ones!!!)

cheers

Ok guys, heres the storey of my A/C woes.

Got the car brand new and within 1000km a/c starts grinding. GEt it checked. They say must be the fan so they order one and i have to take the car back. next service they have to check it again, they think it's the compressor so they try that, short time later noise starts again. Take it back and they decide its the TX valve. problem solvered!!!!!! go figure, these guys no **** all they are just guess and checkers. Don't ever agree to pay nissan to do this work if out of warranty, take it to a real mechanic.

Other problems include the throw out bearing (****ed), faulty front seat upholstery, ****ed fuel sender unit (The gauge), head unit is the biggest dodge job on earth. Resets cd's to 1st track regularly, way overheats, occasionally adjusts volume on it's own.... THere have been other problems but I can't rememer them at the moment.

[Drew]

I drove down tro the beach yesterday in 36 degree heat and the air con was clicking on and off all the time.

the compressor is makeing a horrid rattling gringing noise.

its not only cutting off at the lights, it cust off when driving too, and blows hot air for a while, then clicks back in and i have cold air again... really weird.

and Adelaide is 39 today, 39 tues, 37 wed and 37 thurs....

doh!!!

[Danosssaur]

Mine had done 53k when I got it & the A/C was fine until 1 week after I got it. Now a idle when I'm stopped at the lights it rattles/grinds. I have assumed it's the A/C clutch or the bearing or the drive belt. Service comming up in about 1-2 weeks so they can fix it then. I got a 3 year/175000km warrenty, benefit of buying "pre-owned" car from a major car dealer called Holden. Hope they know something about NISSAN's though :confused:

It's a heaps annoying cause any little noise or rattle in my car drives me mad. :mad:

[Drew]

Well my compressor blew up last night!!!!

Driving home from the beach, sitting at the lights and the car stalled... Started it up, lights turned green and i didnt have to stop at traffic lights for about 5 kms. I also noticed the air con wasnt blowing cold air. I pulled up at the lights and I could smell a burning metal smell and clutch smell. Smoke was pissing out from under the bonnet too. I pulled over and smoke was beltching out from the compressor and a horrid rattling noise was coming from it (sounded like big end bearings in the engine!!)

Looks like the clutch in the compressor is gone, cos compressor makes a grinding noise when its turned off.

Does anyone know if the belt that drives the air con drives anything else - ie power steer etc? I want to disconnect the belt.

I wont be able to get under the car to replace the compressor until the weekend... :( doh!

lucky my mate has 2 spare compressors!!!

Cheers
Drew

Good to see some other people are having problems with their SSS aircon (well not really). Since new mine has made the same low level drone when the ambient is 25+deg.

The Nissan dealer(s) in Canberra has replaced the compressor twice and regassed it three times but the problem is still there. Went to QLD last year for xmas and had it checked out by Metro Nissan who said it was a harmonic on the belt that set in at low revs.

Something to do with the SR20DE having a very long section in the belt. They readjusted the tension which seemed to work for a few weeks but the problem came back. Whenever it happens now if I just touch the throttle and bump the revs up it stops. If it was bearings then it should still be noisy but it still doesn't solve the problem.

The other problem I had was that after three hours driving on the highway the a/c gradually started to get warm. Stop for about 20 min and it would be okay for another few hours. The replaced a valve which apparently was faulty but I haven't been on any long trips since to check it out.

[Drew]

On friday my compressor totally shit itself. not only was the bearing noise really loud, the clutch in it smoked up big time. Had the RAA out and they flicked the fan belt off. I managed to drive to work, then back home running just off the battery. Total driving time of around 50 minutes and about 26kms. I was really surprised my battery lasted with no alternator connected. The warning chime gave me the shits though beeping all the way home telling me the battery wasnt charging.
I managed to change the compressor over in 38 degree heat and with a hell hangover. wasnt fun I tell ya.
So no more noisy compressor, and will have to get it regassed in the new year...

cheers
