I have replaced the 15amp fuses in the fuse box and moved the relays around. I believe it is a loos connection but having the horns below the headlights on the front fascia means I have to remove the front bumper to even get at them. Also hear audible clicks from he fuse box when horn should sound.

If you hear the relay click, then chances are that either you have a bad connection at the horn, or your horns have just failed. It does happen. No way to test for either one without some disassembly.
ahh I was afraid of that. Thanks for the response though.
