Many small problems

Hello to Alle, I’m new here and recently proud owner of a Saab 9-5 2.3 Turbo from 98. Recently some minor problems have accumulated which I would like to solve with your help! – Heating Driver side: Does not work; It only comes cold air. Passenger side gets really warm. What can this be? – License plate lighting: These already did not work when buying the vehicle. Birnchen changed, unfortunately the license plate remains unlit. ngplan für Sicherungen? – Tacholeuchtung: Up to 140 the tacho shines wonderfully, the pear under it is unfortunately dead. How best to get to the pear? How is the amarture board removed without damaging the hozbarten? – Seat heating driver side. Does not work either. Replace seat cushions or rather check tension? If these defects are fixed I am really happy with my Saab. Hopefully not by thousands of Euros poorer…. The Dutchman who lives in Germany and drives a Swedish car… 🙂
