Without A/C working, (or with a low refrigerant level) the climate control cannot cool the air so it just pumping round outside air, but if the A/C has a little refrigerant then it may only be able to slightly cool it. When the refrigerant gets too low it will switch off the compressor to avoid damage.

Quite possible. I've replied to your PM.

Hi!

I was (sadly) in this section about a year ago... No AC on my 2008 2.0i C5 X7 when I purchased it. Thanks to the help of the forum, I found that a pipe was broken (the classic one) and changed it. Then, the car got an AC regas, and it lasted....few days.

Back on this, thanks to the weather...

As it works during few days, and the pipes out...

You may well have a leak from the evaporator box. When they test for leaks, they should either use a 'sniffer' tool to detect the refrigerant for leaks or a UV light if the system has had some dye added to show leaks.

Xantia A/C pipes part compatibility

Hi all,

I'm in no way an expert in air conditioning systems (or cars in general), so please bear with me :-D

The A/C in my Xantia (2000 MK2 HDi 90) has not been working for a while. I discovered lately that the high pressure pipe that goes from the compressor to the condenser has a hole the size of a small pea. I was looking online for...

Have a look below - some of these are still available. Let me know the number on the diagram:

Hi all.
Where is the pressure switch (es?) located?
And at what PSI should it disengage?

What's that last parameter in the first screenshot - it's covered by your windows start menu? .... open cylcle ratio?

If not there, try looking at custom parameters and see if you can add it.

Grand Picasso c4 aircon leak

by J1senter » 14 Jun 2021, 20:48

First post

Hi all I’m hoping you may be able to help. I’ve had my grand Picasso c4 2015 regassed twice in the last 2 years. My local garage can’t find a leak they have put dye in it but can’t find anything. They pressure tested it and it loses 1 bar over 3 hours. Anyone got any ideas

Last post

Leaks can be notoriously hard to find and not always in the obvious places.

You may have a leak in or near the evaporator box inside the dash. There are probes with UV lights or 'sniffers' that can be used to better detect any leaks from these areas.

Having said that, it took the main dealer 4 attempts on 4 separate visits after recharging to...

X7 (and 407) Condenser Hose Repair

First post

Before Christmas I noticed that my AC had stopped working, upon checking the pressure it was completely empty. I traced the leak to the condenser as upon filling with gas you could hear a hiss from the front of the car.

Replacing the condenser didn’t seem like a huge job so I set about that, unfortunately the aluminium pipes were corroded solid...

Last post

Just thought I would update the thread.
It has been 15 months since I made this repair and the A/C is still working well (touch wood).

Would be interesting to have the refrigerant recovered and see if any has been lost, but I'm happy to call it fixed for now :-D :-D

Partner Teepee, No memory in climate panel

Hello all
I have just got an 2011 Partner Tepee with digital bi zone climate control. The problem is that it forgets its current setting every time the power is cut. It then returns to the same setting (22C / HI) which means that the fan goes to max every time the engine is started. I am planning to switch the climate panel as I hope this is the...

On your passenger compartment fuse box, there is a SHUNT fuse, used when the vehicle will parked up and not used for longer periods - it shuts off some of the electrical system to conserve battery power. Check your manual for the position settings, but is should be shunted to CUSTOMER position.

Air con always on (xantia year 2000)

by howzat » 08 Mar 2007, 21:41

First post

My problem is that the compressor engages with air con switch off. This causes fans to operate. Switching on the system lights the indicator in the switch. Unplugging the compressor disengages it. I need a wiring diagram of the system and location of the various relays. Any suggestions would be appreciated.

Last post

Isn't that what air con does. Remove water from the air and dry it.. Hence its use as a demister.. The water is what has been removed from the air and is deposited from an outlet pipe..

Although he has not been on the Forum for a while you might want to give DickieG a shout. He has the proper a/c equipment AND the knowledge about what amounts should be used (either that or where to find that information).

Berlingo Airco problem C72A- B -D -E

by blownelco » 04 Nov 2020, 12:20

Hello,

Need help on fixing my airco on Citröen Berlingo B9 model.
Last summer the airco failed to work, instead of getting cool air it was blowing very hot air into the car.

The hot air blowing stopped by itself.

I checked the compressor clutch and it wasn't working anymore, the coil was burned through.
I relaced the coil, refilled the gas. It...

The motors are simple stepper motors and these (depending on type of climate control or A/C fitted) will control the Air Distribution and Air Mixing functions. They do not have individual ECU in them, so need no coding to the vehicle.

When you say the airco pump in your post above, are talking about the A/C compressor? Of the clutch is engaging...

The new C5 in the family was bought with a non-functioning AC system and a strange metallic rattle sound. After removing the Aux belt and spinning the alternator and air con compressor pulleys, it was clear that the sound was from the AC comp.

Yesterday I replaced the failed compressor with another from eBay that claimed to be working and cost...

Thanks, yeah it really is an amazing piece of design; especially the ability to vary the displacement on the fly with an electrical signal.

Not sure how the shaft could be reconditioned though...

My current car is the first I've owned that has AC... so I'm not very knowledgeable about it!

It recently started making whirring whooshing noises that come and go regularly, usually under engine load rather than idling. If I switch the AC off, the noises go away. My garage thought it was because it was working hard in the heat but it didn't do...

I'm now wondering if I've got a blocked/stuck expansion valve and whether I've caused this.

Air Con Noise - Clutch or Compressor?

I have a problem with the air con on my Series 1 Xantia Activa. After starting the car and switching on the air con, after a few seconds there is an audible click and the clutch can be seen to engage on the side of the compressor. The air starts to blow cold and then the cooling fan kicks in – and at the same time there is a terrible screeching...

Last post

That does sound like an alternator bearing giving up.
Try it again, using lots of lights, heated window, and blower (on high speed) to see whether this sort of load does the same thing.
Under high load, the tension in the alternator drive belt will increase, and put a bigger load on its bearings.
If the alt is the culprit, probably best just to...

Good evening everyone after some help please.

So up untill a week ago my aircon was working fine and the condenser fan would cut in and out every few minutes so no problems all was ok.

Last post

Hi
I suspect that the cooling fan is running as intended now that the A/C has proper pressure and oil etc within the system, it needs to be running constantly when the A/C is running.
I suspect the reason the fan was cutting in and out before was because of low pressure and that would probably have meant that the compressor was also cutting in/out...

Thanks for the replies fellas. There seems to be two approaches to cleaning the evaporator- the bomb method you both describe, and the foam injection technique e.g.: Genuine Toyota A/C Refresher Kit, Power Max Klima Anlagen, CRC Airco Cleaner Pro. The Toyota product uses both methods, and Klima have similar dual products. My thinking was that if...
