Hello and my seat heating is not working on the driver’s side, but only the seat, the backrest is still working, but only very little, so only slightly warm. The switch lamp works. Can it be that only the seat mat is broken??? because I thought that they are connected together so to speak, i.e. if the seat is not working, the backrest is no longer working???? I have el. leather seats without memory. Can it be that simply not a plug or so broken or wobble contact??? Which plug would that be??? I have under the seat of left after Rects 1. White 2. Blue 3. Blue 4. Schwaz 5. Black. Achso side airbag I also have! didn’t want to just pull off all the airbag lights on. Thanks already for your answers Yes have the search used but found nothing with my specific problem. And don’t bit drawings of electro stuff, so I can not even start ^^
