Horn Sounding Won't Turn Off

[Oneilly]

Guys, I posted a problem with my electrics last week, I had lots of flashing dashboard lights ESP Fault, engine running on etc.

The horn also started and won't turn off, this is all without the key in.!

I pulled the natural off the batt and reset the system, i then drove about 150 miles without a problem.

About 1.30am last night the horn started again,

P.S there was no wind where i live.

It's driving me crazy, any ideas?

Possibly the front SAM has got water in.

I take it the SAM is the fuse box, just checked the cover wasn't on properly, drain channels were blocked, hope this dose the trip it starts, no horn so fingers crossed!
