So this is probably a weird one:
I have a V35 (350GT) 2005 - one of the dashboard back-lights, behind the odometer has died or has dimmed, the back-light for the dashboard clock only reliably works/comes on when the headlight sensors determine it's nighttime outside and dim the dashboard/gauge lights, my passenger side interior light only comes on sometimes when I open the doors AND the bloody fuel gauge doesn't work properly (sometimes it reads it's half-full and then suddenly as I drive it points to being full. Ohhhh and my vents will sometimes blow warm air, even when set to the lowest temp - other days it will be fine. (not because of the engine being warm or cold or it being a hot day etc)
Now I'm completely uninformed about the intricacies of cars, but i feel some, if not all, of these issues are connected because; as I drive to work, sometimes in the cold/damp mornings, my clock will be lit up and working and so will the fuel gauge. But a few hours later when I go to get food, back to square one!
So I come here to ask for advice - I don't think it's a the actual fuel gauge itself because of how it all seems to happen together. Drawing on my radio technician background, it all feels like something to do with fuses or earthing issues, but I wanted to see what you guys think first.
Thanks
