think you have taken the seat heating fuse out
there is a full list of fuses here mate
http://www.vxoc.org.uk/forum/Thread-Fuses
there are fuses in the fuse boxes that are not listed
if they are not listed and are there they should be not used
you can get the small fuses from halfords
so it wont do any harm till you get there
the washer fuses can blow if the water in the pipes are frozen
this happens to save the motor from blowing up
it is best to use washer fluid that does not freeze
this time of year instead of water
