In the boo..... : )
It's been a while but if memory serves, you unscrew the 4 white plastic wotsits then remove the boot light surround you can then pull the carpet away, have a look under there.
The boot light uses the same earth connection as the number plate lights, rear side light and rear fogs so trace that wire to wear it screws into the bodywork so have a look to see if its corroded / broken etc
the fuses for the items you mention are used for other things as well, central locking and power windows for example so the problem lies elsewhere imagine.
