Thread: PUMA air-con issues

stretch to call it cool at all. I settled on this as it seemed to be beyond their knowledge or willingness to do any better.

This seams to be where I am at after 3 goes as well Might have to send an email & see what I get back

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.

You are 100% correct.

My Puma is getting it's 20,000km service today and on the list is the AC not working again. They have explained that the "condensor is freezing up" and have kept it overnight to work on it.

My 7 month old Puma has had similar problems, working for @ 30 mins then blowing warm on a hot day. Firstly the dealer said it was low on gas and topped it up, second time they did the same thing. I told then fix the leak as I"m 1500k:s away. Contacted LRA and they replaced the TX valve in Karratha. It then worked better than new for 2 weeks but is now doing the same thing.

Sounds like a job for tracer dye.

I had the same problem in my XJ Cherokee when bought as new, and took it across the Nullabor on 50 degree c weather in summer.

Got to Perth on 46 degree C day in February....

Replaced TX valves, but ultimatey was tracer dye that found the cause of the leak... after seeing local dealer and fixing it, we drove it back and froze all the way!!!!

Well I am still waiting for the parts to arrive from Melbourne.

Hopefully it will be fixed tomorrow (day 3) before the weekend. Going on a trip to the Watagons on Sunday and AC would be nice.

Mine's gone too - conveniently it went a few months out of warranty and after my dealings with LRA I don't think there's goodwill.

MR (wisely) don't mess around with A/C. When I last had it out there they took it to the local auto-elecs who thought it was a sticking heater tap. They zip-tied the tap open and that bought me an extra 10 minutes of cold happiness before the inevitable heatwave struck.

Austral have quoted me "$850 minimum", which if it's simply the switch sounds like $830 labour for a temporary fix!

Anyone in Brissie got any recommendations on where to go to get it sorted?

Good thread and I have the same issue too. 40+ day across the nullabor and it was no longer cold. Add the heat from the floor and I have to admit the wife was not impressed! Yet to take it to the dealers for warranty but I presume this may be an Australia specific problem and therefore may not be resolved quickly

It seems to me its not just to do with the ambient/external air temp, I reckon the air gets pre-warmed somehow in the engine bay plus there’s all that sun beating down on the panels making things hot to touch… it just cant cope. Common theme on here I think. PLUS the in-built Land Rover pie-warmer/ leg-cooker effect after about an hour of driving.

The a/c unit was probably specified with UK summers in mind, summer being on a Tuesday with rain that is *slightly* warmer than usual
