Anyone try Auto aircon in Dublin? 60 quid for a full service. My Saab 93 Aero needs a air con service. Intermittently blowing clod air and it stinks..

He diagnosed a faulty A.C. Pressure switch for me which I replaced myself.
He's cash only, no receipts so that annoys me a bit. There were lines out the door when I got there so he's coining it st the moment!
Great guy.

I got sorted in galway by Donnellan motors in oranmore behind the cinema. Found then very good to deal with. Condenser was gone on mine along with a pinhole of a leak on a pipe!!

kevin65 · 27-07-2018 12:35pm

I got them to check my A/C and they seem very efficient. Got the A/C fixed by the main dealer yesterday. New condenser and seals required.

This is probably a stupid question, but how much condensation on the low pressure A/C pipes would you expect to see in the engine bay? I know the low pressure pipe is chilled so the moisture in the air is condensing on it and forming a small pool of water, but is this just the way it is with all cars? Only noticed as I was checking the engine bay just after coming home with the A/C on full for over an hour.

The colder you run it the more condensation there will be in this weather. Nothing you can do about it

Totally normal.

Agricola · 30-07-2018 6:06pm

Got mine done at Fastfit on the Tramore Rd in Waterford.

€60 for a leak test and regas. All done in hour and a half. Icy cold now. Would recommend them for anyone in that neck of the woods.

LeakingLava · 06-02-2019 4:31pm

Hi guys,

My aircon was intermittently not working and now it is just not turning on at all. No cold air. Hot air is fine. Light on switch comes on when pressed, but still no cold air. I have asked halfords if they could regas, but they said that pressure was okay or that it was actually overly high[can't remember/understand what the guy said at the time] so it was not a regassing issue.

Would anyone have any idea who I should bring the car to? I live in west Dublin, but wouldn't mind travelling reasonably if service provider is well recommended.

Lexus CT200H 2012.

Thanks a lot!

I brought my car to a BMW main dealer recently, and a regas and pressure test., The price was actually reasonable.

I wouldn't hold the opinion of some guy at Halfords in high esteem.

Auto Aircon in Parkwest is well regarded here, but apart from diagnosis, he doesn't do much repair beyond re-gassing. He is good at what he does though, and since you're in west Dublin anyway, he'd be a logical first port of call.

For a full diagnosis and repair, I would highly recommend Brendan in AirCon Automotive. He's just outside Birr, so a long way from Dublin, but he really knows his stuff (especially with compressors). I traveled from Kildare and am very happy I did.

I had a similar issue to yourself in that the refrigerant was full, no leaks but the A/C was intermittent and then stopped altogether. It turned out to be a bad electrical connection to the compressor clutch. Had that fixed by Air Con Automotive and it's been perfect since.

khaldrogo · 07-02-2019 11:04pm

Compressor is probably seized

That's what I was afraid of. Is this a replacement job, expensive fix, or easy enough for a professional to do? Would the 'air-conditioning experts' that I find on Google be able to fix it if this was the case?

colm_mcm · 08-02-2019 9:17am

Are you getting a clunk from the compressor clutch when you engage the aircon? Could just be a relay.

Nothing at all. The car is really really quiet so I would hear something I think. I'll test it out properly later, but I'm pretty sure I don't hear anything when the switch is pressed. Hopefully it is a relay. I will be bringing it to a aircon specialist later today, hoping it's a relatively cheap fix.

Thank you all for the replies. If there are any other suggestions of service providers, please do let me know. I'm only going to this one today because he is willing to diagnose for free.

LeakingLava · 08-02-2019 5:15pm

So I've just been to the airconditioning expert and they have said that it isn't an aircon problem either. They mentioned that it is an electrical issue more than likely. I am now looking for fuse/relay to try and replace them to see if it works after. Thank you guys.

reubenreuben · 29-03-2019 9:30pm

Hi,

Can anyone recommend a garage that does air con servicing in dublin area?

thanks

Atlantic Dawn · 29-03-2019 9:59pm

Used this guy in Park West before.

How did you get on?

I'm interested because I have a 2014 Prius with AC that doesn't work - sounds very similar to your problem.

I did ask a Toyota main dealer to have a look but they just spoke about re-gassing it, even when I specifically asked them to check the electrics. And then they were out of gas so nothing got done.

It used to work fine and now doesn't cool at all. The AC light comes on but nothing happens, no fault messages, diddly.

Hey,

I checked all fuses I could, anything remotely saying anything about airconditioning, and all of the fuses were fine. Until now, I still have the same issue. The expert that I went to said that he was going to get back to me after speaking to a friend which was a Lexus technician, but he never got back to me. I didn't bother chasing as I lost confidence in their service then.

If you bring your car to Halfords, they can confirm if the gas level is right. If it is on the correct levels, then it definitely is a very similar issue to mine. They wouldn't charge you if the gas levels are right as they do 'free checks' which is all that they would do then.

My only other option is to ask Lexus to check it out on my next service which should be next payday. I'll update here if they find anything.

Could be the relay, you should open the bonnet and get someone to turn on the AC when the engine is running to see if you can hear the AC clutch engage, it will roughly sound like a magnet connecting with metal. If you don't hear this most likely it can either me the system not running because it is out of gas or it could be that the relay is gone. If it's the relay that's gone you should be able to open the fusebox in the engine and replace it, probably €25 or so just clips in like a fuse, there's usually a guide to which relay does what underneath the cover of the fusebox when you remove it. I'd try the relay before bringing it to any dealer.

I definitely don't hear anything when the button is pressed, absolutely nothing. Maybe it's the relay, indeed. I'll ask a dealer so I can get one as when I asked a motor factors, they said that relays are dealer only kind of things.

EDIT: A little thing to note as well is that when it all began, there were times that the AC would just kick in randomly and it would've ran perfectly at the time, no issues, no unnecessary noise from the compressor, nothing. So in my mind, it seems like the compressor is fully functional. So it may be the relay alright. I'll definitely spend some time on this again. I kinda just got busy so never really looked into it again.

Jamemid · 22-05-2019 7:47pm

Sorry for the hijack,have something similar of a problem. No cold air from Aircon. Had gas checked and level is ok, the compressor is engaging when the Aircon is turned on. Anyone any ideas,?

LeakingLava · 22-05-2019 7:57pm

Just checked the engine fuse box and there isn't a relay labelled for AC. I was given this from another forum and it's pretty accurate. Seems like there isn't a relay for AC in any of the diagrams.

If the light is on then its a different issue to the OP.

When was the last time you used the aircon? If more than a few months the seals could have dried up and your gas leaked, a pressure check and regas should work. If regularly check the aircon radiator for obvious damage, mine had a massive hole in it.

In addition, the Toyota service rep told me that there were no error codes for the AC. Would an error be thrown if the relay wasn't working?

To answer Dell's question, it's the wife's car so I can't be certain as to how often it was used but I'd guess "regularly" / more than once a month so I guess that would mean the seals shouldn't be the problem.

From what I have seen, it looks like the main dealers aren't very helpful. On the other hand - being a Prius - the AC is different to most cars in that it can run with the engine off. I'd guess this means the AC pump is driven by an electrical motor and not directly off the engine. I'm not sure if a "generic" AC specialist would know their way around a Prius system?

Or to put it another way, could anyone here recommend an AC specialist in South Dublin?

I've found a similar thread on a different forum, but, the car is for an RX 330. Althought not hybrid, the technology involved may be the exact one that is used for our systems.

Ok, your ac system is probably quite a bit more complex than you are aware of. It is not just a signal from the climate control unit to the relay and then to the compressor.

when you select ac, a signal goes to the ac amplifier that in turns sends a signal to the PCM(powertrain control module) which is the main onboard computer. It in turn first checks that there are no powertrain faults that should prevent the ac from running, then its signal passes thru a few more control modules.

From this, it checks the ambient temperature sensor, the ac pressure transducer, and engine coolant temperature sensor.

If no faults found, then it sends a signal to the magnetic clutch relay to turn on the compressor.

As you can see, it is fairly complex. And the first step is seeing if the PCM is getting a signal from the amplifier. This can ONLY be done with a factory level diagnostic scan tool. If it is, then all the other control modules as well as the listed components I mentioned have to be checked with scan tool for proper function and for communicating with the PCM.

IF all these checks good, then the magnetic clutch relay is tested and if bad, the entire junction box replaced. IF good, then clutch has to be tested for intermittent fault and wiring harness tested.

But again, the first step is testing the PCM, which requires a factory scan tool.

If you have this, then I can walk you thru the process. If not, then you will need to have a shop with one do appropriate tests. The only other option is to throw parts at it, which is not economical in any measure

I understand that this is not what you wish to hear, but you have to understand the complexity of your ac system and what is required to diagnose it and the knowledge required for this.

With all this in mind, I myself think that I'm stuck for options and I will have to wait for my service with Lexus to figure out what's going on. I don't think there's anything else I can check. I've even found an onboard diagnostic screen for my car and it is showing no faults. I'll update after my service.

I've just gotten my car through to Lexus for a service and they have said that they didn't see any gas

.

They quoted €100 for them to put gas into it, and told me that the only thing they could suggest is that there could be a leak somewhere but this would be the first thing to do, fill it up and 'see how it goes'.

In my mind, I didn't want to get my aircon temporarily working, and not even get it diagnosed during all that time, so I thought to go to an aircon specialist for a diagnostic, rather than a trial and guaranteed error for €100.

Went onto a specialist today after I received the car from Lexus. After around 30 minutes of troubleshooting, the specialist has gotten an error code using an OBD2 reader/phone app [B1498 Communication Malfunction (A/C Inverter Local)]. He has also completely flushed/re-gassed the system. €50. Now, he hasn't fixed the issue as he isn't a mechanic and the issue isn't something that's obvious, he did common/easy checks but couldn't find fault. He has then advised me to contact a mechanic for this issue to be checked out.

I'll update again as soon as I get a mechanic to look at it.

Anyone could recommend reputable and reasonably priced aircon service facility in Sligo/Mayo/Roscommon area?

Please?
