Aircon Compressor Noise [Archive]

Hi Guys,

Anyone else get this?

When my aircon is on, it is all well and good for a while,

then all of a sudden, while the car is idling and the pump's clutch engages to the pulley a squeel is let out.. it does my head in!,

it's not the belt as it's not constantly happening, only for a split second when the clutch engages..

I have greased the nut end of the pully, and the shaft to the compressor, hoping there is bearings there,

any help would be great,

Cheers guys
Brendan

I also get this, not all the time, but most noticeable when sitting at lights and the compressor kicks in/out.

Would love to know if there was an easy fix, but I suspect it's just wear and tear on the compressor clutch. My Euro has 85k on the clock.

that is exactly what happens to me, I have 75k on the clock.. The oil has been ok so far.. See what happens

Just an update guys,

I ordered the spring from Honda, it has to come up from Vic,

It's $11.00

I can just imaging how much of a pain it's going to be to get to this thing.. bloody Japanese cars! :)

The spring for your clutch master cylinder right? (not the AC compressor?)

hahahah So so Sorry,

I replied to the wrong thread.. I was meant to write that last post in the "creaky clutch" thread..

Once again, so sorry.

But I will update this thread in a couple days after the lube up I did, and post a pic of where I oiled it, if you like?

A photo of where you oiled it would be awesome! :thumbsup:

No probs mate, will try and get one either this arvo or tomorrow,

Can you do direct photo dumps on here? or do I have to do the old Photobucket trick?

I had this happen to my car, i would be at lights and exactly the same thing would happen to mine. One day I was driving home and I hear this massive noise and metal breaking...then I had no air con....blowing hot air....my compressor died. I took it to my local guy and he had to order another compressor. There is a small bolt that the snapped clean in the compressor....cost me $1700

Does this squealing problem only occur when the air-con is turned ON?

For me it happens when the air-con is turned off as well. I don't know where to check. Problem occurs when driving off in first gear, either flat surface or hill. It squeals for approx 3 secs (loud) and then stop. Mechanic can't find the problem.
Hope someone out there can help me with this...where to look and what to do etc.

Don't use ur aircon if that noise comes! Mine did it a few times, then went away. One day i went to use it, the noise was there......then i quickly turned it off. A few mins later, i wanted the fan, but to get fan, i had to press the AC button (to turn it off), instantaneously, the compressor EXPLODED and shattered! So i'd get it looked at first, or else you're looking at a grand to get it replaced.

The belt doesn't have to squeal all the time.
Check the accessory belt tensioner to see if it is at maximum extension yet. The clutch engaging will give an instantaneous load to the belt and can cause it to slip for that split second until the A/C pulley is spun back up to speed.

Aaronng is right. It's the sudden load on the belt. It's not likely to be the bearing as the noise would more likely continue.

This completely slipped my mind..

It may be time for a new belt.. worth a try!

thanks heaps for this.. (I'll check it this arvo)

hi all,

gone through the thread but im not sure if i see an answer to this. mine is having the same issue i suspect, the AC is making a pretty loud (somtime soft) 'Wooop' sound, when AC is on, normally while idle or stopping at the lights.

am intedning to bring it back to Honda to check. But am keen to know if there's a solution to this? or what is the common issue?

I also have the 'whoop' sound when using A/C. What is the official fix for this before it blows up??

- tighten the belt?
- change belt?
- etc?

The whoop noise is from the thermal expansion valve in the a/c system. Unfortunately, it involves removing the aircon gas and your dashboard to get to that part.

Hey guys, i've just had the same problem, which now seems to me a quite a common problem with Euro's. I've lost my compressor clutch mechanism. I just wanted to know what are the best ways to fix this problem without sacrificing an arm or a leg. Is there a way to replace these compressor clutch mechanism, without changing the whole compressor? Is there possibilities of seeking compensation to fix this problem as it's a common problem?

Cheers

The aircon clutch fault is not that common. Most common is the thermal expansion valve and the exploding compressor. Easy to remove though, brcause the clutch is an electromagnetic one. Just need a good pair of circlip removers that is deep enough to get into the middle bore.

sounds costly and troublesome.

anymore details on this aaron?

is there any harm if we keep using the AC?

Mine started a year ago. I've got an 05 Euro with only 43k on the clock. Brought it in twice and dealer said could not detect sound! Really annoying as it happens irregularly and the whine or squeel sounds terrible.

Brought car in for a service today and technician said this problem was raised with Honda Japan but no response from Japan so far. Prime suspect is the expansion valve rather than belt. Changing the valve will cost $600! And no guarantee that sound will go away. The other option is a re-gas. I was told no customer has opted to spend money to try and rectify so they are just putting up with it.

I like my cars quiet so I'm close to trading the Euro for a Golf GTI.

Has anyone managed to solve this issue?

hi hi (newcomer)

ive heard the 04-06 euro's all have aircon compressor problems from factory. my 06 euro compressor was told by T1 that it might blow if i keep using it, its making a very serious vibration when its turned on.
T1 said u can either buy 2nd hand for around $500 or buy new for $1600. I have a friend who's friend had the same problem and he managed to get compensation from honda, now i dont really know if this is true or not and i tried searching google about this common problem with 04-06 euro ~ havent got anything yet

Put me down for a group complaint. Mine is 2005 Euro Lux Manual. I want it fixed properly but would appreciated if honda compensates part of it.

If your car has full service history with Honda then you can put forward a case to Honda for consideration.If they do they'll supply the parts and you'll have to pay the labour.

My 06 Euro just started making the whoop noise. I have 3 weeks left on my 5 year extended warranty. Would Honda replace the expansion valve under warranty? I recorded the whoop noise on my phone for evidence.

Yes, make an appointment now! Don't wait until your warranty has expired. Even the phone recording's date won't be enough to persuade Honda Australia. Make sure you show them the sound when you drop your car off in case they can't reproduce it.

Thanks for the quick reply. I just called my local dealership to make an appointment for next Monday. As expected, they gave me the usual bullshit about how they never heard of this issue before. One of the mechanics will come for a drive with me. I will make him listen to the recording and just hope that the car makes some sort of noise during the test drive. But just in case, I will also bring a complaints form from Consumer Affairs Victoria and fill it on the spot if they refuse to fix it. From the various threads on the issue, it does not seem like people have been too lukcy with getting it fixed by Honda. Thanks again for the heads up!.

Make sure that they admit that they hear the sound before your warranty is over and have it logged into your car history/case. Once they have that logged in, and if it fails after warranty is over, you have a better chance in still getting it repaired under warranty.

Yep, I will make sure the mechanic does not leave my car until he hears the noise and I will ask for a written report if they refuse to fix it. Just one last thing: do you reckon there would be some sort of 'optimal' conditions for the noise to be heard? like setting the temp to a minimum or fan at maximum or in gear vs neutral? Thanks.

i too have a blown compressor. quoted $2800 for genuine, $2300 non genuine from Honda and $1800 from local radiator and air con workshop.

common problem. this compressor must be that bad. head over to the tsx forum - not just an Australian thing thats for sure

Yeah, i told the guy from the dealership that it seems to be a common issue with euros and crvs. His reply was "never heard of the issue before" and "don't believe stuff you read on forums".. idiot! did yours do the whoop noise before it eventually failed?

aiutn

08-11-2011, 02:12 PM

yeah got spun the same story. local guy said he fixes them all the time. Mine stopped with no warning or notice. even when i turn the a/c on it doesnt make a noise and i thought usually when a compressor seizes it makes a loud squeel. im hesitant to even replace it, some guys over on the tsx forum have gone through 3 compressors!

There are 2 different sounds. The WHOOP sound like a wolf whistle is the thermal expansion valve. The aircon will still work and cool the air.

If you get a grinding rattling sound, then the compressor's stuffed. In this case you don't get any cool air out of the vents.

Sorry to revive an old thread... Recently my car have a weird sound coming out (seems to be the compressor) whenever the air cond is switched on. Wonder if this is a sign of the compressor clutch( or the compressor itself) is failing? Thanks all

Actually you should revive old thread instead starting new one. Search ftw. :)

sounds normal to me

but, when was the last time you got your a/c gassed?

LETZGO

25-04-2012, 10:24 PM

With the Woop sound does that lead to the rattling in the compressor I have an 06 Lux with only 40km and I can hear the woop, it happened offen when I first got the car but slowly it has slowed down and the air stating cold. So I am unsure how to approach the issue I am a mechanic and thinking of taking it to a good frien who owns a air co/ auto electrical place......
Not sure what to do arrrh!!!!!

26-04-2012, 12:07 AM

Sounds like you need to re-gas the a/c

The sound of the compressor engages is pretty loud, sometimes even louder than the engine idling :S. I'll try to get another comparison video to show the difference soon. The air cond is recharged roughly 3 months ago due to a leaky hose.

Oh the loud engage? That's normal, I've lived with it for 9 years.

have u had ur compressor changed before? mine sounded like this and soon after that it decided to blew up itself so had to get a new one and noise was gone. My mechanic reckoned that the 'oil' inside the compressor isnt there anymore or gone for some reason thus it ceased up and blew. if you ever have to get a new one i would recommend JM auto air just google them should pop up first thing first, they are located in Sydney and i got it for 400 shipped and installed for 50 bux as well as regas for 120.

hope that helps

Hey guys,

When i had my CL7R everything was fine. I just got myself a 2007 CL9 limited edition, and i got this loud high pitch noise or squeel when I turned on my aircon.

It happens when the conpressor kicks in and when the car is stationery (both in N and D). Is it the belt? Has anyone resolved this?

Cheers

Remove A/C belt
If noise is gone
Something powered by the A/C belt is done for
Spin the pulleys individually
Could be A/C bearing on its way out/ Alternator bearing on its way out
Or tensioner
