Since today the lighting for the temperature setting on the passenger side has failed. You can still read the set degree number with good light incidence, but also not more. You can also change it. Have already tried the search, but unfortunately found nothing right. Can someone help me and tell me what to do now. Should I drive to the Opel dealer? Or is it only a small thing that you can fix yourself? Do you have the problem that my car from Sonnt ag is elsewhere again and I can’t fix it. So I would have to manage everything tomorrow? Would be very grateful about your support!!! If it was only due to a light source, I would be pleased about a very detailed guide. I find it ugly if it is not illuminated. Thank you!!!!!!
