Up until today the air-con was working reasonably well.

Today, with the temperatures set to minimum the best I can get is warm air from any vents (warmer them ambient).

If I turn the air con off the warm air gets much hotter giving me the impression that hot air is being mixed in.

Any ideas please, I've tried nearly all the combinations of settings I can.

I have a two day trip planned, starting tomorrow - is there any way I can shut off the hot water supply as a temporary measure until I can get it sorted ?

Any help would be appreciated - TIA.

2005 RRS 2.7 V6

Had exactly the same this afternoon. Aircon was fully re-gassed a month or so ago and held a vacuum for 20mins before being pressurised.

It was about 35 degrees in the car at least and I noticed when switching the air con on the recirculate button illuminated. 20 mins of driving and it was still giving me very warm air out of the vents. Switched the recirculate button off and things seemed to cool down a bit, but still not really cold like I’d be expecting.

Luckily it’s now in the garage having the front crank oil seal replaced, so have asked them to investigate the air con as well.

I’ll report back, but be interested in thoughts from those more experienced on the L320 air con system than me.

You could try a hose clamp on the drivers side under the bonnet.

Read the fault climate codes

When was it last re-gassed? 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Condenser is a prime candidate,, happened on mine,, they have a habit of corroding along the bottom edge. Pulling a vacuum for 20 mins is not a good test. Re-gas with a dye and any leaks will be easier to spot, also make sure it is filled to the correct charge or it will never work correctly. 2010 RRS, TDV8

I could try clamping off the "heater" hose but have not got a clue which one it is.

Also, the A/C fan is not running.

It was last re-gassed about a year ago.

It's booked in Friday at an air con specialist so I'll report back afterwards.

Which AC fan ?

Compressor is easy enough to check and rules out a major part of the system,, you should be able to hear or see the clutch pulling in when your assistant switches the AC on. Even a small leak will empty the system in days 2010 RRS, TDV8

These are variable compressors. So you don’t hear them click in and out.

Fill valves are a common leak point on these. Nice and cheap

Thanks all for the input - will see what the garage says.

Thanks for all the input so far.

Gas is up to spec but the compressor is not running, nor is the fan - booked in next week for further diagnosis so will have to wait & see..

It looks like the compressor is faulty, so wallet prepared for emptying.

Mine’s a new condenser, £100 plus £30 regas at the local National Tyres. Worth investigating a used compressor ? Plenty around on eBay
