Moin together, I have an electronic problem in my Volvo V70 II. Although the vehicle is off and closed, the fan for the interior is randomly operated at the highest level. This can happen after 20 min or after 5 hours. Quite randomly. The blower then until the battery is empty. Then I always have to turn on ignition and it goes off again, or on the adjustment which is in the air conditioning. Therefore, I always jam the battery as soon as I get the W the next morning the battery is empty. I have already changed the climate control unit, got a used one from Ebay, but didn’t do anything, the car still does that. Vlt. there are here which could narrow down something I should look for. Thank you very much, MFG Sascha PS: Sorry, I landed in the wrong subforum, can you still move the thread?
