Failed MOT on.....Horn and handbrake! (also heater blower)

How ironic after doing so much to her in the last 3 weeks to get her ready for her first MOT in a long time, to fail on these.
Any advice on how to sort the horn would help, i seem to remember the heater blower and horn are on the same fused circuit, but i cant bloody find my manual. Any help on which fuse and relay it is?
Many thanks
Mark

horn fuse number7 = 15 amp, relay k2
heater blower fuse number 20 = 30amp/relay k7

Thanks mate
Went out to check, the heater blower fuse was broken, replaced it and still nothing. But now when its turned to setting 4 it makes a chunky kindof click after a couple of seconds, its not the relay clicking its something else behind the dash.
As for the horn, very confusing, it works but only if you turn the wheel to the right as you press the horn

Thanks, tried searching but i cant find any threads with the same problem, only ones where the fan only works when switched to setting 4(full) which is a knackered heater blower resistor pack.
