The horn button actually completes the ground. If your horn isn't working then the ground wire going to the horn is broken. Horn technology was an undiscovered, unresearched, unresolved thing back in Sweden in the early 1960s - mid 1970s. When I got my 1974 Sonett a few years ago, my horn didn't work. I looked at the wiring diagrams it all looked very simple. I then looked at my steering column down low and there was this coil of wire wrapped around it. At first I just dismissed it as some DIYer's fascination with using too much wire but then I realized (and others on Saabnet advised me) that this is the way it was done. So I checked out this wire and somewhere there was a break in it. I fixed/replaced the wire (with prudent coiling around the steering column - checking to see that it didn't bind up with a complete turn in either direction). Once fixed/replaced all was fine in horn world.
On my 1971 Saab 96 that I got last summer I noticed that only one horn was working. I checked out the other horn and the wiring was disconnected. I cautiously connected them ... the horn worked.
I found that most electrical issues on the 95/96/97 (Sonett) models are related to a bad ground, a corroded connector or fuse or a broken wire or poor/non-connection.
Good luck.
