No power to horn on drivers side

The horn that chirps when the locks are set doesn't work. It's not the "remote programming" fix.
There are 3 relays that check out OK. The horn works fine on test but is not getting 12V from the plug when the horn is blown. Any ideas?
Thanks in advance, Martin

Nope to both posts. Fuses are OK as are the relays. All 3 Relays were removed and bench tested.

Run a wire from the battery + to the horn and see if it sounds, if not, theres your problem.

Horn works fine wired direct to battery.

OK - problem solved.
I missed the fuse marked ANTI THEFT located at the bottom RT hand corner in the fuse panel beside the battery. Close inspection revealed corrosion on the spades and the fuse blown right at the corner not the middle. I suspect the corrosion caused a poor connection which spiked the current when the doors were locked and horn chirped.
Thanks to all that helped.
