French Car Forum

Hi all,
I have checked the forum and could not find an answer for my question so i am posting it.

I have a 2009 Citroen C5 X7 and last year I had no AC. Took it to a shop, they charged me 100€ and said the issue of ac not working was a bad pipe.
Ac worked during last summer.

1 year later, no ac again. I believe the shop scammed me with some stop...

Hi, my AC is acting up.

I have a strong feeling the inside temperature sensor is faulty, due to the fact that the climate system acts like the temperature is very high.

Do any of you know where it is located on a citroen c3 II bluehdi 100?

I tried to remove the plastic panels on the footwell on both sides, i found the aluminum pipes but can't...

Hi All,

2014 DS5 2.0hdi with an intermittent aircon issue (VIN VF7**************[VIN obfuscated, can be read by forum staff]

The car has spent the last 2 days at an aircon specialist with no luck other than the issue is electrical (system evacuated, pressure tested and re-filled with 450g R134 A) . The issue presents as follows; When the vehicle is first started (from cold) the aircon...

Hello. Does anyone know how much air conditioning agent should go into a Peugeot 508 GT? Agent R1234YF.

2013 DS5 2.0 Hdi, 230k km.
Aircon started to cycle, couple of minutes on, couple of minutes off, etc...
Car went to three workshops (one of them Citroen), none could fix the problem.
Replaced high pressure sensor and brightness sensor.
After last workshop visit the aircon only works 30 seconds after engine start.
Tried bridging low pressure...

Hello everyone, I am new to this site as it is my first time owning a great French vehicle. I have a 2002 Berlingo. I recently started having trouble with my Air conditioning. The compressor does not kick in when I push the button on the dash. I had an electrician look at it and he said the report suggested fan modules. Does anyone have any ideas...

Hi everyone, I hope someone can direct me on this one.

I was dismantling the lever arm from the air conditioning system behind glove compartment ( car is left hand drive). it is held by two rotating shafts ( top shaft extends out 2cms to couple on lever arm plus adjoining cog and the bottom shaft extends by 1cm to attach the other end of the...

Hi all, my brother picked up a 2008 C4 Picasso which he loves but it has the blower fan for the heating going full chat all the time. I’ve been fiddling with it to try and sort it but so far we’ve tried the following with no change;

- changed the resistor that sits into the bottom of the fan itself and also checked voltage. 13ish volts down the...

The ride is a 2005 407 2.0 petrol.

Lately the ac has been cutting out by itself while driving i.e. the internal blower fan will just died suddenly. Sometimes it will go on running back again after few secs but sometimes it just died. Stopping the car with ignition off & starting again sometimes help, but sometimes won't until the next day......

I am desperately trying to get my car back on the road, I bought my LH drive Picasso from new in the UK, the cooling fan motor for cooling the engine and air con stopped working, seems to be a special and can’t get one anywhere anyone any ideas why it is special and any way around to use a standard fan.
I will try to post a picture

Hi have a petrol 1.4 c3 rythem 2008.

Had the car for a year the a/c was sort of working last summer. But if you turned blower upto 4 it would start coming out normal temp on 3 it would work.
This year during hot weather went to use again
Only one dash vent comes out slightly cold (not fully chilled) the 3 others blow normal air you would expect...

Thank you for having me in this group. I have just joined and made a donation. I appreciate any help you can give me.

I live in Portugal and today I have just bought a silver 2008 Xsara Picasso. It's our second. We moved here 2 years ago in an Irish registered Picasso of the same year.

I was aware that the AC wasn't working but the seller took...

Hello to everyone , i have a common issue but i still need your help. my parents got a c5 back in 2010 or 2011 second hand. For most of the life span of the car we did not have ac, and many times they tried fixing it , it worked for a couple of months and die again. recently i got my license and they gave me the rights to the car. as we are all...

Hi

I've got a 2011, 1.6 THP x7 c5.

Lately, the passenger side temperature setting doesn't work. it is set to 22.5 and cannot be changed.
All other buttons on the panel are working. I can set the output (window, face, legs) on passenger side, activate the auto mode, etc.
This car doesn't have a single zone (or at least I didn't find a way to...

The RT4 Head unit on my vehicle (Peugeot 407sw) has developed a fault which I am unable to cure with the RT4 Upgrade CD which the display is asking for. I performed a BSI reset in the vain hope that it might cure the problem with the Head unit which had been working perfectly well. It would appear that the BSI reset has resulted in the AirCon...

Hi great people here.

TLDR: New AC blower motor died in very hot day. No voltage at motor.

I have issues with my Aircond blower. Last month it starts behaving weird especially in hot afternoon after I leave the car in the sun. Initially, the blower will die after few minutes running. Then I found out if I put the speed not at the max (like 75%)...

Hi everyone,

I'm very happy to have found this forum! I seem to be having the same problem Janko was describing in this post:
With the heating turned all the way up on both sides I only get hot air on the driver's side. On the passenger's side the air coming in feels like outside air - cold, winter air.

So, I assume the heater matrix is all...

Hi all, I have an issue with the internal tan motor not working when fan speeds increased.

I replaced the resistor once before back in October 2022 and I’ve just dropped the fan down from the housing and started the car and the fan is spinning on low speeds. Even when the fans turned off it’s continuously running.

Is there anything else I can...

I have a question & hoping someone can help, i had someone come look at my car with diagbox (abs problem) but since then i have no heater or aircon. Would anyone have a setup for a c4 grand picasso mk2 as im getting my own setup now as twice ive had someone look at my car & its been worse after

Hi all, I have a leak from my high charging port shrader core and have found the following tool on many UK ebay sellers that claim you can change it while the system is charged.

Has anyone used these on French made cars as the only reviews I can find show American made cars which I believe use a...

I am Aneesh from Portugal. I own a Citroen Xantia 1.9 TD (1994). Recently my AC compressor stopped working. I refilled the gas into the system but still have the same problem. I thought maybe the pressure switch is defective, and replaced it with one from a friend's car, but it still doesnt work.

To check things further I bought a multimeter...

First off vehicle details :)
1999/2000 2.0 Hdi MK2 current mileage 89262 verified :)
Vin is in my signature ;)

I have had my fair share of Xantia's and this particular one was bought 11 months ago as a needs must replacement, i knew the marque and i never thought i would get my hands on another one.
I sort of know the relay system for the fans...

Hi, I own a peugeot 205 forever. When the car arrived in Israel in 1999, the main company that sold peugeot cars installed a local addition of an A/C to the car. The compressor itself is very efficient in terms of cooling output, apart from the fact that when it is activated, a decrease in the vehicle's engine power is felt because of it’s...

The fan stop working and i got, correctly, the fault-code is correctly saying no correlation between actually fan speed and command.
I do have two old fans from C5 series II. There is only one difference, the small connector being three pin on the older Series II, and four pins on Series III, X7. The rest seems compatible.

Does anybody have the...

Hi everyone,
Hoping someone is able to help me.

I have a Citroen C4 Picasso 2012 model.
The air conditioning was great, until around December.
In December, the vent system flooded due to the panel under the windscreen clogging up. Since then, the air conditioning doesn’t blow cold air.
We’ve had it regassed - they said they tried it twice. They...

My other half has a 58 reg Grand C4 Picasso - on the whole it has been very good to us and is a nice car. However we have an issue with the AC only blowing on either maximum or on the second to highest maximum setting (digital displays on the outer edge of the car).

I would assume this is some sort of resistor issue usually, however I'm puzzled...

Good evening,

My 2006 C6 has an issue with the Air Conditioning where the drivers side is always wanting to blow ridiculously hot air regardless of what temperature it is set to. The passenger side appears to be working normally.

I've plugged Diagbox in to watch the live data that shows the temperature of the air being blown on each side of the...

After a repair a few years back when the condenser was replaced and happily working, my air con has failed on the van.

Returned the van to the same repair workshop and they diagnosed a failure in the high pressure line from the dryer to the firewall area, cost £400. I intend to try and repair this myself by firstly finding the point of failure...

So I have a 2012 Peugeot 3008 HDI Allure
My AC is behaving weird. At first it was working fine when you had run it from start when the interior of the car was cold (eg in the morning from the garage)
?t would not work when you had the car standing in the sun. Lateron it is totally random. You can force it to run by turning ignition on and off and...

Hi, I'd need some help please to identify correctly the compressor for the A/C of my Peugeot 406 2.1TD Break from 11/1997, as it is leaking and because of the impossible quote the specialized garage made, I'm going to order myself a new compatible compressor and my mechanic who I usually go to will install it, and only then I will go to the A/C...

Hi!
I have a recently acquired 2014 5008 1.6Hdi. I had come to the conclusion that this had R1234YF refrigerant in it. I now have my doubts. I cannot get a low side coupler to fit, designed for R1234YF, and I understand these ARE a different size to R134a fittings. Has the place I got my info for type of refrigerant lead me astray?
Thanks.
Phil

Same issue on my C4 Picasso, checked the compressor and the clutch isn't working but I dont have a diagram to fault find it back, has anyone got a wiring diagram for the Air-con system please. Thanks

So I've got a 2010 Peugeot 308 T7 and the A/C stopped working. The compressor doesn't kick in. The system must be full of refrigerant because I had it serviced two weeks ago and there are no visible signs of leaks (the a/c oil has a UV dye in it but I couldn't identify any leaks).

I noticed the following very peculiar live data:...

Hi all,

I have searched, and found too much information, but none of it relevant - Trying to locate the pressure sensor switch on the Xsara Picasso.

Air con has been regassed and holds charge.
All connections around compressor have been checked.
Compressor doesn't kick in. Can hear a click, but neither front fans come on, AC doesn't work.

I'm...

Hi
I have an unusual problem with the air conditioning. Compressor clutch coil does not engage. The coil is operational, it works after applying voltage directly from the battery. I measured the voltage on the coil power harness and it is strange. is only 10.8V. The voltage appears when the engine is started and remains even after turning off the...

Hello Guys,

Hope some of the bright minds here can help with a air con problem on my 2010 C5.
So far I have had a friend try to diagnose the problem without much luck so far.

When switching on the AC, the AC light comes on, but the air blowing into the car does not get cold.
The clutch on the compressor never engages, hence the compressor does...

Hi to everyone. First time on here. Hope someone can help me.
Last week I removed the stereo unit and aircon climate control panel to replace a broken ashtray and when I fitted it back together the climate control is stuck in 18°, the fan stays on and can't be turned off, the CD changer doesn't work and side electric mirrors don't go up and down...

Hi all, new here so thanks for letting me join.
I have a problem with the aircon on my Citroen Relay 2010 L4H2. The aircon turns on and works ok on fan speeds 1 and two. As soon as I switch to speed 3 or 4 the aircon cuts out and the light on the aircon switch turns off.
Has anyone else had the same issue or know what my problem is likely to be?...

I have some weird noises on my C5, I think they can be heared the best in this video. Of course, the problem is not only the noise, but also some weird behavior: The temp is set to 22 degrees C and, while it's cold outside, the right side of the vents would blow cold air while the left would blow hot air. Other times, the left would just have hot...

Hi, I've been reading the various threads on the forum but wonder if someone can help me.

I've acquired a '98 Xantia 1.9TD left hand drive, in amazing condition inside and out.
Only issue is non functioning A/C. Being in Southern Spain that is an essential!

Had the gas checked by a mobile service and there is gas there. He is on hand to vacuum...

I am putting the red light on the temperature gauge, rightly or wrongly, down to the air con not working.

Read an interesting post on here about the Air Con ECU not have a dialogue with Lexia. Whatever I do, mine will not come up. I am left wondering particularly in light of my next comment whether Citroen just ended fitting a different Air Con...

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...

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...

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

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

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...

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...
