Problem with the air conditioning and heating in the 2013 Citroen DS5 Diesel: causes and solutions

Hi guys, I have a problem with my 2013 Citroen DS5 Diesel. The air conditioning is only blowing warm air and the cooling/heating isn't working properly either. I think it might be the faulty signal from the air quality sensor, but I'm not sure. Have any of you ever had a problem like this and can give me a tip on how it was fixed in the workshop and how much it cost? I would be really grateful for your experience and advice.

Hi, I had a similar problem with my 2011 Citroen DS4. I would describe myself as someone with a bit of experience in cars. At my garage they replaced the wire/cable from the sensor. It cost around 95 euros to fix the problem. Could you please give me the exact vehicle information so I can give you more details and help further? Hope this helps you!

Hey, thanks for your quick reply. I recently had my DS5 serviced at 15651 km mileage. So you think it could be the cables? I would appreciate more details and thank you for your help!

No problem, that's what we're here for. In terms of mileage, it could well be the cables. In the DS5, just like in my DS4, these are known to become brittle over time. If the cables from the sensor to the air conditioning system have a loose connection, the air conditioning system gets the wrong information and goes crazy. In the workshop, they normally check this by measuring the voltage on the cables. If the values are irregular, then they replace the cable. It's not a big job and, as I said, it cost me around 95 euros. Maybe that will help you. Report back when you know more!

Hey, that's really helpful information! Didn't know the cables were so notorious for becoming brittle over time. All right, I think I'll have it checked at the garage next week and see if that is indeed the problem. Your information on the cost is good to know, it helps me to estimate a budget. I'll get back to you as soon as I know more about it. Thanks again for your help, you really have been a great help!

Hello ! I've changed the air-conditioning blower 3 times, the last time a month and a half ago. It's a calamity on this car and the technicians are very often helpless to find the origin of the breakdowns (sensor, cables, blower). It's annoying and especially at this time of year when garages close for (deserved) vacations. I don't know what to do or where to turn to solve these problems.

Hello, In the event of such a fault, I would recommend that you look for a workshop that specializes in repairing air conditioning systems. The air conditioning system is a very complex system which should only be repaired by trained specialists.

Hello, good afternoon. I have a 2012 Citroen DS5, and the cabin fan and resistor have broken down. The repair shop told me they installed an aftermarket one, but it doesn't work well and that it has to be the original brand. Could that be true, or are they trying to pull a fast one on me? I'm a mechanic, and I know it's very unusual for that to happen with a car that's quite old and the part isn't super difficult to replace, thanks.

Hello, good afternoon. I have a 2012 Citroen DS5 and the interior fan and resistor have failed. The workshop told me they installed an aftermarket one, but it doesn't work properly and that it needs to be the original brand part. Could this be true, or are they trying to pull a fast one?

It's possible that the aftermarket part isn't performing as well as an original equipment manufacturer (OEM) part. Aftermarket parts can sometimes have compatibility or quality issues, especially with electrical components like fans and resistors. If the aftermarket part isn't functioning properly, it might be worth trying an OEM part to see if it resolves the issue. Keep an eye on the performance after replacement and let me know how it goes. If you have any further questions, feel free to ask!
