[CL9] Air con compressor clutch not engaging

So the air con has suddenly stopped working the other day. There was no gradual drop off in cooling, it just blew out ambient air. I went through a lot of the posts in this forum and anything I could gather from the interwebs.

Symptoms:
The compressor clutch doesn't engage when I turn the A/C on.
Only ambient air is blown through the vents.
No squealing noise coming from the compressor or engine bay.

Does this sound like more than just a need to re-gas or something else?

I found this on the web about diagnosing compressor clutch problems on the UK Accord using the US Accord schematics (which looks identical to the CL9).

Except for testing if the relay is faulty, are the other tests safe to do?
What else can I check?

Thanks.

Apparently if there's either too much or too little gas in the system it can cause the system to not cool properly.Go to an auto electrician and get them to regas/check the system and put some dye in it while they're at it.

I have a feeling there is also a pressure valve that can stop the compressor actually turning on too.

Was it working at the time that it stopped, or has it just been something you have only recently turned on after a few months. You may have heard the power increase on the car if the a/c was on at the time it cut off. Could be a relay/fuse but technically a fuse shouldn't go unless there was a problem it was trying to protect the electrical system from.

I took it into the local NATRAD this morning and was told the compressor is completely dead... urgh! Waiting on a quote from them.

Was quoted $1200 for a Delphi compressor + labour + regas... ouch!
$500 for labour + regas alone.
$700 for the Delphi compressor.

Does that sound reasonable?

Was thinking of getting this compressor from eBay that comes with 5 years warranty.

That's reasonable for the compressor
One thing you need to ask
If they do replace the system
Enquire if they do flushing/refill with correct PAG oil
Otherwise all those metal shavings will kill the new one
i'd suggest do some shopping around for the best price
Might be a good idea to see if you can get a price on a Hadsys/DENSO one (OEM Makers)

Booked in with Frozen Air in Keysborough (VIC). $1200
- Sanden compressor (his suppliers don't stock the Denso ones for Euro/CRV anymore - too many warranty replacements)
- New Condensor (with drier)
- System flushed
- TX valves checked/replaced
- re-oiled, re-gassed with dye

I can't be bothered looking around anymore... tired of the Mrs complaining about no aircon :D

Maybe try take the compressor into a place like Ashdown Inrgham and see if they can match it up, might get one for around 300 bucks if its anything like earth-moving gear I deal with


edit ^ oic, at least its sorted now lol

I did mine in Sydney from a mobile repairer for $1200 cash.. total.

You're paying too much there mate

Good compressors.

the Japanese DENSO compressors are rubbish.

Im in the process of getting my aircon compressor replace after it shit it self and seized. I got quoted $680 to fit compressor, replace tx valve, new condenser and flush.

Brand new compressor and TX valve from USA cost me 330 shipped. New condensor cost me 100 from ebay seller in Sydney.

Do you think $680 is fair for the above install of parts only?

HmM, the missus accord euro recently started blowing ambient air from the AC. Had done this intermittently after running for a while previously, but now it's permanently not working.

Common for the compressor to crap itself on these is it?

A bit of thread mining. The compressor on Management's car has also stopped playing. The clutch does not engage, the revs don't pick up etc. I've checked fuses, haven't had a meter out yet to check power to the clutch, but after reading through the thread it looks like a cactus compressor could well be on the cards. Not sure what services around Hobart are like for fixing aircon, but if it's like everything else, with a small population and a captive market, things tend to be expensive unless you know someone in the game.
Does anyone have a part number for the Sanden compressor for an '07 Accord Euro Luxury?

Cheers,

Mick.

I don't remember the name but there is an air con compressor rebuilder in Melbourne.

Buy it. Have it shipped down. And get any aircon shop to do the fitting.

The compressor for all the accords of the same vintage is the same.

Thanks for that. The unit on the car is a keihin hs110r, Summit Racing have them new on Ebay for Oz $345 including freight. I'll do some more homework, but that looks like a good start. There are several vendors selling clutch kits, at least that way I'd be able to do the work myself. I've yet to measure voltage at the connector to make sure that the clutch is actually getting power, nothing worse than replacing parts that were serviceable.

You can use a flash light to look at the compressor clutch. The outer ring will be spinning and the centre will be idle when A/C is off. When A/C is on, the clutch engages and the middle will spin as well. If the middle spins but you don't get cool air, then the compressor is the problem, not the clutch.

If you do replace the compressor, I would transfer the old clutch pulley over. The aftermarket ones have slightly different diameters, thus needing you to determine what new belt length you will require!

I finally got around to checking the power to the clutch with a multi meter. It doesn't matter what A/C setting I select there is no power to the clutch, if I apply 12v to the clutch wire it engages. I've checked the few fuses or relays that I could find reference to in the glovebox handbook, so unless someone can point me at other likely culprits, I think I'll get an auto electrician to have a look.
