Managed to coax all the electrics back too life. Initially nothing worked then the hazards started flashing and one indicator. A bit of spraying and rapid movement of the stalk and bingo, all working. Side light were ok then the headlights came on after leavening the switch on for 5 mins. I think the car just needs using and is sulking after not being loved for so long. Brake lights worked fine and the wipers even self park. Managed to even get a sprinkle of water out of the squerters. Just need to get the heater controls back together and the car will be complete again.
