Hi, a similar thing happened to me with my 2018 Toyota Corolla. I have a bit of experience with cars, but I'm not a professional. At my garage, they discovered that the control unit for the electric fan was faulty. It cost me around 480 euros to replace the control unit. Could you please share more information about your car (how many kilometers it has run, whether there were other previous problems, etc.) so that I can help you better?

Hi, thanks for your reply. My Avensis now has 122496 KM on it and the last service was without any problems. Before this problem it always ran like clockwork. I will take your advice to heart and have the control unit checked. Maybe that really is the problem. Thank you!

Hello again! Yes, checking the control unit would be a good step. That was the main problem with my Corolla and after replacing it, everything ran smoothly again. Your Avensis has already driven a few kilometers, so such problems could occur from time to time. Hopefully you will soon be rid of the problem. Please let us know if that was it! Good luck and keep us up to date!

Many thanks for the helpful advice! I will have the control unit checked in the workshop and then keep you up to date. Thanks for the good wishes, see you soon!
