Jaguar XF fuse blowing

Hi All ,
I have a Jaguar XF 2010 , I got in it the morning and had no radio but also noticed no power to climate control heated front and rear screens .
Traced fuse to the boot fuse box what was no26 and it was blown but as I replaced it it blew straight away seems like I have a dead short somewhere .

I would agree. Time to pull out the wiring diagrams to narrow down the places you’ll need to look.
