Bebop2018 Posted July 20, 2018 Share Posted July 20, 2018 Hi All New to this forum and hoping someone here can help with an air con issue on our Fiesta 1.4 Mk 7 - 2012 When the air con is switched on, there is an underlying whirring noise. More annoying and noticeable inside the cabin of the car, around the dash. We purchased a replacement compressor to resolve the issue, or so we thought, as the noise only appears when the air con compressor engages. This noise still remains despite a change of compressor and regas. So, confused as to what to look into next. The local air con specialist thought the noise was our imagination and did say prior to the replacement compressor, that this was not the problem. Nonetheless, we changed it anyway, but the noise is indeed still there. . Please help!!! Paul Quote Link to comment Share on other sites More sharing options...
northern-matelot Posted July 20, 2018 Share Posted July 20, 2018 I have the same issue with mine, only recently started. I turn the air con off and the noise stops. Turn it back in and I hear it after about 2-3 min. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Bebop2018 Posted July 20, 2018 Author Share Posted July 20, 2018 At least not on our own, though it has cost us about £250 so far and that was very cheap as our friend who is a professional and excellent mechanic changed the compressor for us, otherwise it would have been a lot more! our car never had this air con noise up until the last couple of months and the car itself has only done 39000 miles, so not even high mileage. I hope someone out there can offer any further suggestion on this..... Quote Link to comment Share on other sites More sharing options...
Treef Posted July 22, 2018 Share Posted July 22, 2018 I also get this, I thought maybe it's the rad cooling fan that comes on as soon as A/C is switched on. I was going to run the A/C with the fan disconnected but I don't know if it would cause the system to overheat. Quote Link to comment Share on other sites More sharing options...

The Aircon will only cool the interior with airflow through the condenser, via fan stationary or via airflow from driving. So disconnecting fan will stop Aircon working when stopped.

Bebop2018 Posted July 22, 2018 Author Share Posted July 22, 2018 I wonder what else is connected to the air con from the engine? Not the compressor, so thought maybe it was some other pulley or belt that comes into play when the air con is switched on. Whirring sound seems to come from whine the dash board - in the centre... Ish! Quote Link to comment Share on other sites More sharing options...
sioneon Posted July 23, 2018 Share Posted July 23, 2018 When I've got out the car the past few days with the air con on there has been an almighty fan blowing for a short while afterwards, no air con and no fan noise. My wife's Mazda 2 diesel would do the same too so would write it off as an air con standard feature Quote Link to comment Share on other sites More sharing options...
Bebop2018 Posted July 23, 2018 Author Share Posted July 23, 2018 The noisy air con is not a standard feature, as this whirring noise issue only started a couple of months ago. We also have three other friends and family who have similar model fiestas with no issues whatsoever. It is a strange one though and is rather irritating to listen to when driving. It needs to be resolved somehow..... And not by turning the radio up! ;0) Quote Link to comment Share on other sites More sharing options...
Bobr Posted July 24, 2018 Share Posted July 24, 2018 I've been using aircon a lot lately and it isn't at all noisy. However, when the engine is switched off I can hear the fan running for about a minute afterwards. Quote Link to comment Share on other sites More sharing options...
Eatonm112 Posted July 24, 2018 Share Posted July 24, 2018 I have a 2015 Fiesta eco boost and had a similar issue in that when I was stationary in traffic the AC/ rad fan would come on and I would hear a very loud whirring sound and feel some vibration in the cabin area. Upon inspection I found that the lower coolant hose had come loose as the very cheep and flimsy clips holding it in place were broken once I re clamped the hose the sound stopped another this I did notice whilst doing this is that the radiator moves around quite a lot!

Bebop2018 Posted July 25, 2018 Author Share Posted July 25, 2018 None of the above issues are relevant to this issue sadly. The air con is manual control. I understand though, about the cooing fan continuing after the car has parked. That is usual of all cars, including y Honda Civic and nothing to do with the air con issue we are having with my wife's car. The noise is heard within the dash area.... Or so it seems. Still a mystery...... Quote Link to comment Share on other sites More sharing options...

dp45uk Posted August 28, 2019 Share Posted August 28, 2019 Hi , I have the same issues as originally described in my 2014 1.25 fiesta just wondering if you ever managed to find a solution to the problem ? Quote Link to comment Share on other sites More sharing options...
Treef Posted August 29, 2019 Share Posted August 29, 2019 After I had the A/C recharged it is a lot quieter, you only notice the wirring sound when you first switch the a/c on then it goes quiet. Quote Link to comment Share on other sites More sharing options...
hopefirmhouse Posted August 29, 2019 Share Posted August 29, 2019 Mine is a 1.25 Fiesta 2014 also and odd noises when air con is on, like a ghostly rotating sound that isn't normal. Had a new compressor and air con clutch and re-gas apparently, but still the same. Can manufacture the sound by switching air con on and lifting clutch in first gear, then the strange noise which is not normal as have had previous fiestas, any ideas? https://1drv.ms/v/s!AnUU69HpI17bgeA32svYOatQvxQjUg Quote Link to comment Share on other sites More sharing options...
LondonFiesta Posted September 1, 2019 Share Posted September 1, 2019 Mine was fine until I had the aircon serviced and refilled, same rattle noise. It still works ok though Quote Link to comment Share on other sites More sharing options...
Wicko Posted September 11, 2019 Share Posted September 11, 2019 I’ve just purchased a fiesta 2016 Mileage 18000, after a hot summer the air con has been on a lot. There’s been a strange noise in the cabin from air con, it sounds like a small water fountain within the cabin. I’ve taken it back to the dealer who had it on the ramps to check if there was a blockage but the condensation was flowing out of the drain pipe fine. It’s been back to ford under a warranty and they believe there isn’t anything wrong with the air con. But the noise is still there I’m taking it back to the dealer this weekend. 🤷🏼♂️ Can anyone help with this issue. Quote Link to comment Share on other sites More sharing options...
Deemo1 Posted September 12, 2019 Share Posted September 12, 2019 I notice the same noise on my fiesta zetec s a couple of days ago🙈🙈 as my aircon comes on automatically after turning the key( providing the blowers are already on!) I get the whirring/whistling noise also. Could there be a small fan in behind the dash that could be making this noise? Perhaps due to condensation from the air con pump being blown through the pipes, causing the bearing in the fan to whir/whistle?? Quote Link to comment Share on other sites More sharing options...
WalkingTractor Posted July 15, 2020 Share Posted July 15, 2020 Just had the same happen to my 2012 Fiesta 1.25 edge,a strange whirring noise from behind the dash when I switch air con on but goes off when air con off,compressor bearings all ok etc,any ideas as seems to be transmitted through maybe pipes rubbing somewhere possibly? We've had the car 7 years without this noise?Did anyone find out the answer please? Quote Link to comment Share on other sites More sharing options...
Treef Posted July 16, 2020 Share Posted July 16, 2020 I had this on mine last year but strangely after I had it re-gassed the noise went away, whether it's pure coincidence or not I don't know Quote Link to comment Share on other sites More sharing options...
1968 Posted November 29, 2020 Share Posted November 29, 2020 I've got the same.noise on my 2014 ST. Its an harmonic bearing noise coming from the aircon when it's on. Its more evident on a hot day and the pitch of the noise goes up and down with the revs has anyone has anyone had joy yet? I've had it regassed twice and its made no difference.

Benc1704 Posted April 21, 2021 Share Posted April 21, 2021 Got the exact same problem here fiesta 2013 1.6 automatic.. whirring goes up with the revs.. no clue what to look into Quote Link to comment Share on other sites More sharing options...
Rob.Bee Posted May 20, 2021 Share Posted May 20, 2021 My car went into Fords this morning for the noise when the aircon is on..just had a phone call to say it is some sort of air con pipe but it’s needs to be ordered...I’ll up date when I find out more and when it’s fitted to see if it sorts the noise Quote Link to comment Share on other sites More sharing options...
