Increased heat instead of cooling: experiences with the Opel Insignia's air conditioning system

Hello, I drive an Opel Astra from 2018 and had a similar problem with the air conditioning about a year ago. Instead of cool air, only warm air came out of the air vents and in general the function of the system was impaired. I suspected it was the coolant, but after a trip to the garage it turned out that my air conditioning system was leaking. This was a serious problem, because without a functioning air conditioning system, the inside of the car becomes a sauna in summer, while in winter it is almost impossible to prevent the windows from misting up. A few parts had to be replaced and the system refilled, but in the end everything worked perfectly again. To date, I have had no further problems with the air conditioning. I hope that helps you a little! Greetings

Hey, thanks for your answer, really great! I would have guessed that your problem was with the coolant, but it's interesting that it was something completely different. Do you remember the cost of repairing and replacing the parts? And did you have any further problems after that, or has everything run smoothly since then? Many thanks!

Hey, I'm glad I could help you! Yep, the costs were definitely not without cost, but what can you do, that's the life of a car owner, right? I ended up leaving €495 for the repair of the leaking air conditioning system. Fortunately, everything has been fine since then. The defect in the air conditioning control valve was fixed and since the visit to the mechanic, the air conditioning has been running like clockwork. So, no further problems. Sometimes you just have to invest something to get things running smoothly again in the long term, don't you? Hopefully this makes your decision a little easier! Best regards!

Hey, thank you very much for your feedback and the detailed cost overview - that helps me a lot! Yes, you said it: sometimes you have to invest a bit, but if it works again in the long term, it's worth it. I'll make an appointment with the mechanic tomorrow and tell him about your experience. It sounds like he pretty much knows what to do. Thanks again, you've really helped me out! See you next time and have a good trip! Best regards!

Hello I drive opel insignia B grand sport year 2018 2.0 diesel I have the following problems with air conditioning Somewhere air conditioning is leaking, I was at ATU they did investigation 3 people almost 2 hour nothing found Today I was at Opel workshop for air conditioning maintenance (filling) So the air conditioning was empty so it must not be completely empty the master said somewhere is leaking. The master has again made examination with 2 people again nothing found ... everything fits And now he said he has to do diagnostics, which means everything has to come out from the inside. to find the fault, because under the hood everything is ok Costs should not go over 3000 Euro so between 2000-3000 Euro fixed Does anyone have any tips on what the problem could be? Thanks in advance

Before going for a complete diagnostics which can be quite expensive, you might want to try using a UV dye in the air conditioning system. This dye will circulate with the refrigerant and will leak out wherever there's a leak. Using a UV light, you can then spot the leak. It's a relatively simple and cost-effective method to detect leaks in the system.

This could potentially save you a lot of money if the leak is in an accessible place. However, if this doesn't work, then a full diagnostics might be necessary.

Thanks for the quick reply.they have already done it all, with the beep device too.two weeks ago inside the car on the cockpit, front air sistem a few drops of water splashed out on the window.maybe there could have been a problem somewhere.but that was only once, and it was raining outside and I didn't think anything of it.

Hello, the drops coming out of the air vents, is that really water or could it be coolant?
