Dampness causes all sorts of weird problems when cars get older (and the
rubber seals around electrical connections start to age)... I wouldn't say
rain water was shorting out the horn (a true short would cause a fuse to
blow)... I would say the water caused and open connection (breaking the path
for current to flow)... Could have even been cooler/warmer temperatures, or
vibrations - we had a speaker in our old 1991 Golf that would randomly start
and stop working (for days at a time, or cutting in and out at random)...
And a headlight that for some reason when out... I got mad at the car,
kicked the bumper and the light came back on :-).
Crawl under the car and look at the connections on the horn if you want...
But those are all permanent style connections - the first connections that
tend to go are on contacts (in the ignition, or the horn buttons/button)
Do you use your horn a lot? (seems like it)... I never seem to have to use
mine, I wouldn't even know if it started to act up for weeks... Volvo horns
seem to have a good enough sound to wake up other drivers, but if yours goes
completely you could always wire in an air horn ;-).
