85 320i electrical problem (onboard computer panel and check light)
The problem is, that the onboard computer panel lights do not react at all (they dont lit up) when pressing the button. Also the check light in the dashboard is lit up all the time. What I've noticed though is that when I turn on/off the front lights (pulling the lever out and pushing it back in), some lights in the panel react aka they flicker just for a moment.
As I've removed the floormat and the bottom cover of the steeringwheel, it's the best time to check any wires that might cause the problem. So please give some advice what might cause this issue since I have no clue about electronics.
