Hey team I'm in desperate need of some advice. I was trying to see if the fuse was blown for the window washer motors as they aren't working and the car is booked in for a wof/mot tomorrow. There were a few fuses missing, so I did foolishly place 2 fuses where I thought there needed to be a fuse, I also removed most of them and reinstalled as none were blown...but now my cluster has gone completely blank. Never happened before. The centre screen works fine and it will turn off/on if I remove fuse 18 but not the dash cluster. I've left the fuse out and battery disconnected over night to see if it resets over night. But if not, has anyone else had this issue? I will work slowly through the fuses again tomorrow but what a pain in the ass! The cars sold with a deposit down waiting on that crucial wof! Eeeeek! Please any suggestions on what to check? Are there other fuses that cause this to stay off?

thanks team, first post for me so hopefully I've covered everything.
