Hello, because I have found nothing about the search function I open a new topic here. If I have been blind, please excuse this. I need your advice. I bought a used Aveo year 2011 from the dealer before not even 4 weeks ago. One day before the run an inspection was made according to manufacturer’s specification as well as TÜV. Here is a guarantee for the and the parts. This also includes the air conditioning and the blower motors. The day before yesterday I was my car washes on such a box with high pressure hose, because I still fight with the wax layer on my windshield, which makes me almost blind in the morning during rain and oncoming traffic. Since yesterday evening, the ventilation, which can be clearly heard at levels 3 and 4, makes a kind of noise of blow every few seconds. So it blows and blows and blows and in between always comes a short push, which sounds as if an extra push is given again. One second. When I turn on the air, it stops, otherwise it is to be heard on all available settings, with and without climate, warm as cold. Blatterwerk is none under the windscreen wipers in the ventilation. Now I have to determine what exactly is broken to check whether this falls into the warranty performance. Has anyone experienced this similar and can tell me what components or errors are in question? Thank you very much in advance and a nice weekend all On the other hand,
