Nissan Repair: Nissan 240SX, nissan 240sx, test light

Question
The horn on my 91 240SX stopped working.  It doesn't seem to be a fuse, any ideas?

Answer
Mindy,

There are a variety of reasons for the horn to stop working.
The horn could be bad.  This is the easy one to check.  Get a test light and connect the clip to ground and disconnect the wire at the horn.  Have someone push the button and see if the test light illuminates.  If you get a light replace the horn.  If not check the relay and if the relay is good then it is the horn button on the steering wheel.
