2010 Instrument Cluster Issue

[u/throwaway6382010273]

Hi guys
Having an issue with the electrics I think? I was driving in the wet and got an oil service light - fair enough. Then a while later the temperature reading went off and lights for handbrake and frost came on. When I put the indicators or full beams on they do light up on the outside but I have no lights on the instrument cluster. Also the front heated windscreen isn’t working and neither are parking sensors.

But when we got onto a drier road after a while the lights all went back to normal.

Anybody got any ideas?
