I've also had a problem with my horn (in a 77 Olds Delta 88) and can't
find any repair information either. I can hear what sounds like a
relay flipping in the vicinity of the fuse panel whenever I push the
horn, but there's no other sound.

The horn on my 1983 Toyota corolla (2 dr sedan)
stopped working. The fuse for the horn/hazard light
is okay. All fuses in the fuse box in the left kick panel
and the fuse box next to the battery under the hood are okay.

What should I be checking? The Toyota repair manual does not
discuss horn problems at all.

Thanks in advance.

hold down the horn button and at the same time pivot the steering wheel

forward and back. if the horn blows when pushing the steering wheel

forward the horn contact is bad.

The easiest test for a novice to determine what the problem is is as
follows: try to power up the horn directly. Run a jumper wire from the
battery to the wire that goes to the horn. Make sure that there is a good
ground. You can do this by running another jumper wire form the negative
cable of the battery. If the horn works, you have another problem. In
other words, it's not the horn itself. Toyota's have a common problem
with the horn contact, which requires disassembly of the horn pad on the
steering wheel. If that gets too involved, you need to take it to a shop.

One of the most common horn problems is a rusted out horn. Manufacturers
usually put the horn in a very exposed position (down low close to the ground
so that the sound is not muffled). Take a meter or test light and crawl under
the car, find the horn and disconnect the connector. Have someone press the
horn button and check for 12 Volts on the wire. If you get it, the horn is
rusted out inside.
This has happened to me twice so far.

Agreed. If memory serves, on this car the horn is below the right side
headlamp. Another unusual detail I found when trying to diagnose this
same problem on my brother-in-law's Toyota was that it doesn't use a
relay. The problem on his car turned out to be a bad wire in the harness
between the horn and the firewall; we ran a jumper wire to fix it.
