Air conditioning in 2003 BMW 6 Series only blows warm air - possible causes and solutions

Hello, I once had a similar situation with my 2005 BMW 5 Series. The heater fan was causing trouble. Really annoying in winter! My garage checked it out and found that the temperature sensor was due for replacement. It was probably a minor issue. Your problem sounds similar in terms of symptoms, so it could be a similar issue. Of course, it could be something else, you'd have to have it checked. But in any case, it wasn't a death sentence for the car in my case. Good luck with it!

Hey, thanks for your answer! Your experience sounds really similar. Can you remember how much you had to pay to get it fixed? Have there been any further problems since then or did everything go smoothly again? I'd love to hear your feedback!

Hey, since I've been to the garage, the fault with the temperature sensor has been rectified. So I'm quite happy about that. However, it cost me €155 to repair the line. It wasn't cheap, but since then the car has been one-a-okay and I've had no further problems. Hope this helps you and that everything turns out well for you. Good luck, buddy!

Hey, that sounds encouraging. It's always good to hear that other people have had similar problems and have solved them. So, €155 is a bit much, but if my car runs perfectly again afterwards, it's worth it. I will contact my mechanic and ask him to have a look at it. Hopefully everything will go well. Thank you again for your helpful reply! Take care and hopefully you will be spared any more car problems. See you next time!

Hello Marc I recently had the same problem. I went to my friend and had him check whether there was still enough air conditioning gas in the system. Fortunately, everything was fine and in the end it was a faulty plug on the air conditioning compressor. I hope it's only a minor problem for you too Have a nice evening

Hello, In my case it was also the case that the maintenance of the air conditioning system had been overdue for a long time and some refrigerant or air conditioning gas was missing. After the service, everything was ok again and has been working ever since. I think that the employee at the garage had said that maintenance should be carried out every 2 years.

Hello everyone. My air conditioning condenser had a small stone chip, which was not immediately visible. My trusted mechanic topped up the air conditioning gas with UV agent and a few days later the leak was localized using a UV lamp. New air conditioning condenser and filling and the air conditioning worked again like on the first day. Perhaps another idea that can be checked very quickly.
