Blower does not go out, despite ignition, where is the fuse? Kangoo BJ 2003

Hello, I have an old Kangoo from 2003, gasoline 1.2 16 V, KC is the name of the model I think. Since yesterday the blower in the interior no longer goes out, can not be regulated, blows full polle, even if the car is off. Have all fuses tried one after the other, but unfortunately none found, where it would have gone out. Is there another fuse box somewhere with the Kangoo? Or can one take off the aperture, on which the controllers sit? To look there, whether you can pull off a cable or a plug? My neighbor then has the battery disconnected from me, otherwise the battery would have been empty this morning. I found in the internet so far only that there is probably a resistance broken, Ok, I can then let me look again next week, but what do I do now, with every stop the battery disconnect and then again, if you want to continue is also not so much. Can someone help me, how I blow the now e can rest until I can drive into a workshop? I had the same experience. already with my VW bus, the heater didn’t go out anymore, there was then the fuse or the relay under the driver’s seat… Thank you!
