Pouring over the wiring diagrams for the problem I have, tracing the current path to the front accessory socket, it runs via F1 and F6 via the passenger accessory relay.   Haynes is a bit light on relay info TBH. 

There is power at F1, although there is no current flow, as though the circuit is open, but shorted to earth via my tester its there.  Done same at F6, nothing.  To my mind this suggests the relay is poss duff, My Haynes says the relay is in the passenger fusebox but there's nowt but

Right, having located the relay in question I want to check, my next question is how the hell do I get to it?  Mounted atop the passenger fusebox.  

Is it a glovebox removal job?
