If the refrigerant charge is good and the compressor , healthy the expansion valve can be declared the culprit only if the ac is not cooling.

The expansion valve is what provides the refrigeration effect(liquid flashes into vapour state and that is how the chilling takes place).

If the expansion valve is not working even with a normal refrigerant charge it would indicate:

• abnormally high hi side pressure eg.400psi
• abnormally low hi side pressure eg.150psi

In your case,I see no issue

BTW , the hissing should not cause any concern

Listen carefully when a brand new direct cool refrigerator is running - you'll hear some gurgling/hissing - does anyone bother about this noise?

And now my brand new 2012 Ford Fiesta Classic 1.4 TDCi - the a/c cooling is pathetic. Any inputs?

Current ODO 1700kms, hardly 30 days since purchase. Experiencing poor cooling during the daytime since Day 1. I thought it was due to the summer heat (Iam in Blore). But when I drove a Wagon R and a Beat Diesel, I realized I have issue with my a/c. It isnt even cooling even after a 30 mins travel in hot sun. Always I have to keep the blower in 3rd or 4th to atleast 'feel' that there is some a/c. Though, it cools reasonably well during the night and I put in 1st or 2nd blower. Should I start getting very very upset having sold my 1.5 yr old Swift Diesel last month ?

Note: Unlike Maruti, I am not able to find out the a/c pipe glass window where you check for bubbles. Can anyone help me out plz!

Note2: Noticing HUGE water condensation from the center of the car. Looks excessive to me.

Check the cooling in other fiesta for a comparison when you visit the service center

I have a feeling your temperature control ring is set about halfway - hot+cold air mix

Please check if your ac is on recirculation mode,the temperature ring is set all the way to coolest(blue band) and the compressor switch is on (silly but still !!!)

Also if you see water condensation inside the car,the evaporator coil drain pipe must have come off ; please get that refitted

Since most mechanicals are same between Fiesta Classic and Figo, I am tempted to think that AC would be same as well. If so, there should be an issue in your car as Figo AC is quite good even at temps in excess of 40'C. Is there any mention in the manual about compressor size of fiesta classic?

[vnabhi]

@sam_sant2005-----Please get your AC checked by the dealer. The Fiesta and Figo have the most powerful AC in the given segment.

My Fiesta's AC cools nearly twice as much than my WagonR. Only when temperatures soar above 40 degrees do I put the fan speed on the second slot: the rest of the time slot # 1 is chilly enough.

As someone said, please check the heater knob's position and also the air-flow knob. I hope the air is not directed to the windscreen in defrost mode.

Thanks, but I have had those things right! Dont feel silly bcoz people do make such mistakes and these are definitely the basic troubleshooting steps.Though I have been following cars for the past 15 yrs so these misses not for me ! And hey the condensation is not inside the car. Its right from the center of the car BELOW the car. When I park it somewhere after a run it wets the whole area.

My understanding is that Fiesta Classic and Figo share these things - Engine, Dashboard, Steering Wheel, A/c and Suspension.

Iam down with a flu. So planning to take the car to the Service Center only by this weekend. Before that it will be good to have as much information as I can to avoid a revisit.

The condensation is a normal thing ; no worries

Please get the system pressures(Hi side and low side) checked ; that would throw some light

Does ford use some other technology? I have not seen this in any of my previous cars - M800, Esteem and Swift D. Initially I thought the radiator hose gave away!

[vigsom]

^^ No, not at all

The a/c reduces the humidity of air inside,so the water vapour gets condensed on the outside of the cooling coil(evaporator) - that's what you see on the outside.

Once you switch off the ac and park the car,you'll see approx 200ml of water which would have drained out of the evaporator casing.

anyways,keep the forum updated on what happened.

I invariably find water droplets below my Waggie after swiching off the car, when the AC was used.

Ditto for the Fiesta.

I own a 5 year old Fiesta, the AC is really powerful. I always have my blower speed in 1, rarely 2, and never in 3,4. It cools the car in about 10 minutes, then I either have to switch off the AC, or set the cooling adjust knob to the 10 o clock position.

The condensation is normal, no need to worry about that. Take your car to FASS, and check the cooling gas and for any leak in the AC hose pipe, which is a common problem in Fiesta.

Edit: Just realized its been a month since the last post in this thread. Any updates Sam.

+1 to your views, but in my case, the car cools in 2 to 3 minutes, and not 10. Even if I park in the hot Hyderabad sun, it does not take even 5 mintues to cool down. And it is around 42 Deg Celsius here.

Condensation mostly means, the AC is working OK. Check the fan for proper functioning, and the ducts for leakage. Also, the cabin air filter.

Hi Guys,

Our Ford Fiesta's A/C is not cooling.
The problem had first occurred in 2011 (car purchased in 2007)
The service guys replaced A/C Core for Rs. 11k and then it was fine until last 2-3 months when the cooling effect deteriorated.
Now it does not cool. Went to service station again and they checked for the leak.
Came back saying it is happening again in the core and it has to be replaced.
When I asked about having it changed only in 2011, the service advisor says that it is possible that it reoccurs and is a common problem in Fiesta.

He also says that warranty of the core is only 10k KMS or 6 months from the date of installation. Hence it is kinda expected.

Confused. Any help much appreciated.
