Thread: PUMA air-con issues

well... after reading your problem i would say it is almost exactly the same as the problem i was experiencing and i too had attempted repair twice.... but i think they fixed it 3rd time. (touching all the wood in the house). its been about 4 weeks and everything seems to be as cold as it used to be when the the car was new. from memory they changed the whole core so the dash had to come apart. if they are not accessing behind the dash they are probably not changing the right part., ask them to call purnell motors in sydney and ask for Jamie if they need clarification - they will know who you are asking about!!

I have a slightly different problem to you guys, hopefully some one can shed some light.

Mine stays cold, just sweats. Around the fixed dash vents it condensates, and also causes the windows to condensate.
It doesn't seem excessively cold, and usually happens on humid mornings I've noticed. Any ideas?

My 2010 Defender 110 is in getting its first 6 month service today. (Only done 6,500kms as I catch the train to work.)

I reported that the air-conditioning stops working after 30 minutes in hot weather when I dropped it off this morning.

Turns out that it was missing half the refrigerant it should have in it. It has been re-gassed I have been told to monitor the problem.

Beckford.

the condensor is freezingup..

simple to check..

run the aircon ensure that it is dripping water onto the floor.

drive round till it stops blowing cold air.

park it in the sun with all the windows wound up.

if it keeps dripping water for more than a couple of minutes. its the condensor freezing up

not having pulled one apart the temperature sensor for the TX valve is either too far from the core or its cracked the pitot tube and this means the TX valve needs to be replaced.


Big red had this issue from new opening the vents solved it temporarily untill I got it sorted under warranty. In my case the clip that held the temp sensor had come loose and the sensor was about 2 inches away from the core, the aircon rocked untill it iced up.

Thanks for the reply's people, i am having an on going issue
They have put the 3rd thermistor in & guess what.... yer same problem I have told them that others have had done to fix it & even given them the name of the dealers you guys have put on here & told them to ring them. But they don't seam to like that idea.
We had a 1700km round trip on the weekend & asked them what it was they exactly wanted me to do with my $55k new vehicle that lacks air con, I was promtly told to turn the air con off every 30 minutes for 10 minutes & let it defrost
I had to keep it together, I remember why I hate this dealer & didn't buy our new pride & joy from them
Is there any point emailing Land Rover Direct, or am I just better off persevering with these clowns until they finally get it right

Hi All, I have had the same issue with my Puma aircon, on my 3rd Thermistor switch and second aircon compressor now. What you guys have described is pretty common with the aircon working outstanding for 15-30mins then dying/freezing up. I had a LR mechanic tell me the Thermistor switch is the main issue in them, he tells me they are poorly made and what happens is LR in their infinit wisdom and desire to have a Defender with real aircon reduced the operating thermostate temp to low (half a degree higher would eliminate the problem in the first place) which pulls more current thru the thermistor switch. The crappy thermistor switch constructed with very low quality solder melts and shorts out circits and control chip in the thermistor switch. Apparently LR are currently prepared to simply replace the cheap switch (bout $20 I believe) rather than fix the switch and repair the problem permermently. After having an electronic wizz mate of mine look at the issue he thinks he can either repair the switch with better solder or make a replacement part to fix my problem permermently.

i thought i was unlucky that mine was starting to play up at 7300kms
and its nearly due for its 2nd service, i'll keep all this info handy as i'll need it in the next month or so, when it gets called in

thanks for all the grear info
cheers

Again the aircon needed work. After 20min the cold air turned into warm air and there was very visable icing on the aircon pipes in the engine bay.

The first time it happened Sydney Landrover changed a sensor near the compressor but it only lasted 6 months.

This time landrover are aware of the problem and have a fix for it involving pulling the entire front dash off, removing the evaporator and replacing the de-icing sensor.

This was performed by the local Darwin dealer who, as expected, stuffed up the re-fitting of the dash and my stereo and turned it into a 3 day job including a monor recall.

Aircon works as it should now, fingers crossed.
