Technical 2005 Ducato MoHo No Brake lights

[lancepar]

Hi,
Brake lights not working. I have the Autotrail manual but from the wiring diagrams I can't place the fuse.
There is a fuse box under the bonnet and one either side if the cab dashboard. All fuses look OK and I've tested ones I suspect might have blown.
Now many years ago when I started towing our little car, there was a problem which blew the MoHo Brake light fuse but I can't remember what the number was and where, I think it was in the LH cab fuse box.

Because I can't find the fuse I have attempted to remove the brake light switch. I can access the four wires to it (I can supply the colours) but the switch itself is very hard to remove so I gave up. I have a meter but don't know what wires to check it electrically.

Any help welcome.

Found my Ducato owners handbook and found the Fuse F26, it had blown!!!!!!

But why had it blown???

Very broadly allocation of fuseboxes is Engine Bay (B001) covers basic items such as engine and horn and headlights, together with optional ABS, Aircon, and Auto Transmission. LH Cab fusebox (B002) covers sidelights and other acessories. RH Cab fusebox (B101) covers option pack items i.e. central locking, power windows, rear window and mirror demisting.

Layouts for B001, and B002 attached for future refereence. Please note that there s some customisation on both diagrams. B101 is under review.
