A/C Not Up To The Job

[Witchdoctor]

The A/C in the new 90 i not impressing during our summer heat wave it was only just keep me cool with the fan on 3[bigsad][bigsad].
Is this a problem for all Defenders if so is there a fix?
As its only 8 months old i would not think it would need re gassing.
Do i have to put up with it.

Cheers

I assume you'r talking about a Puma engined Deefer?

If so, your A/C should be pretty good - mine keeps the car cool in the high 40s no worries at all (and mine's a 110).

I own a 2012 D90 and live in Perth and the air con is perfect even when it is hot for days on end

[Benz]

yeah sound's like something is wrong there...

if so get it fixed under warranty quick smart.

and if it is working properly... just be glad your not the owner of a pre ford defender ;)
although the air-con on the older fendys are pretty good at cooling your knees!

[timandcarly]

I am a goose. Perhaps you are too.

The other day, I turned on the A/C in our Puma for the first time this season and was left feeling quite warm...

until I realised the fan was still blowing as a demister!:o

Click. Click

Fan blowing through the vents again and I'm back to being slightly too cold.:D

definately get it checked out by the dealer, my 2010 Puma 110 is icy cold with the air con on, but SWMBO complains that she ends up with a cold shoulder (funny, I normally get that....) on one side and hot on the other due to the vent placement, or if shes driving (????? yes she does drive it - off road as well...????) cold left knuckles and hot right ones - I figure your blood eventually flows through both so some cooling must occur.....

[camel_landy]

Try a re-gas but failing that, just wind the window down & drive faster... :D

i have a My12 D90 in white with the leather, and My AC is ice cold even when its smoldering outside. . . Id check that your fan is pumping air to the right place, or jump under the bonnet while its running and listen for any nasty sounds form the air con compressor. . . but if shes knew. . just take it into the dealer and say 'fix it' its a warranty job after all. . .

Mine (MY11 90) works pretty good for the first hour or two.

After that the heat from underneath forces it way through and out competes the cool air.

Looking into some heat insulation soon.

Ha ha same goes for me, can always feel that heat rising. I put setting on knees and face to help cool below.

Heat insulation for future as well.

Has anyone tried using 4/60 air, it's been working faultless for many years. Can't go wrong and most reliable option.

Interesting reading. Was doing a fair bit of city driving yesterday (hot/muggy) and thought the a/c was a little limp after a while. Well, when in traffic it was limp, when moving it got better, so the above comment stacks up. I had a quick feel of the floor/tunnel area but didnt seem overly warm though...

Post up here what you decide to do about heat insulation.

I have also read about thermostat failures - car is still under warranty so was considering seeing if I could get the dealer to change it out prior to warranty expiry (little white lie :angel: )

I also live in Perth and after a cool winter it hit 35 deg last week and i thought the aircon wasnt up to scratch. Then I realised the lever was on flow through ventilation for the winter demisting.
I flicked over to recycle and the temp dropped dramticaly in a few minutes.

Best option is to drive an old Tdi air con equipped Defender in the heat for a few days, after which the Puma - no matter how bad it is - will seem cold.

[Samblers]

Haven’t tried this. I typically leave it on flow-through (fresher air). In fact I heard a Dr Karl (triple J) podcast some time ago where a caller asked about a/c in cars on recycle mode causing a build-up of CO2/ reduction in O2 levels in the car and therefore increased driver drowsiness. Just something to ponder…

[slugworth]

I flip.

Recycled when on the road so not to breath in exhaust from cars in front

Fresh air when on the track to create pressure and keep the dust out

Not sure if any of this works but sounds good in theory

That is correct....Recycle, in any car, used indefinitely, can cause drowsiness.

The heater control valve on the Puma defender is closed by the control cable pushing rather than pulling, on mine the cable was bending and not fully closing the valve, resulting in heat from the heater despite the control selected to fully cold.

There is a very large gap in the plastic air box that comes from the vent top of left guard. Where it joins the second section going to aircon box.
Jaybo pointed out to me that you can slip your fingers in the join quiet easily and its only a piece of thin foam a the join. This can cause hot air from the engine to be sucked in. To help over come this I fitted a air scoop on top of the guard vent that force feeds air through the box. I will also have a go at sealing it better when I get a chance.
