Had the front bumper off for another job and found one N/S wire had corrode and parted; crimped a new joint and it seemed to work for a while (don't use the horn much) but then went to single tone (not sure if it was the same one again) which became a bit hit and miss but now I've lost both.
The relay in the passenger side fuse box is clicking so it must be something at the front (again). I have a spare pair of horns (with plugs) and the matching O/S wing to slam panel loom. Before I have to remove the front bumper etc. yet again, has anyone suggestions of any other possible fault and, is there an easy way to test my spare set-up works before I commit to the change over.

I'm not sure if that sounds like a factory set up as even the single horn from the factory had the proper connectors so may have been a retrofit before you got the car??
I does sounds like the existing connections may have corroded again , so your horns 'may' be ok just need fresh connectors and maybe some wire depending on how badly they have corroded.
To test your new horns could just try some spare wires from a car battery direct to the connections on the horns themselves and that should work ok.
