Vauxhall Astra electrical issues - windows & rear wiper

Hi there.Over the weekend, my rear wiper stopped working (you can hear the click when its switched off but doesnt move). Also the electric windows & mirrors not working, and the LED on the rear window demister stuck on (doesn't seem to be working either).No lights lighting on the window switches. All these things seem to happen at the same time. Any known issues with this? Earthing issue or fuses? I@ve checked some of the fuses I thought were problematic but doesnt seem to be the issues. Has anyone got a good fix for me, please. Cheers.
