check the hazard/horn fuse in the engine compartment.. it might be loose are starting to blow... assuming you have an '85 with the factory alarm.. the lights/horn system is tied together

84-86 - the slip ring gets worn down. If you pull the steering wheel (I recommend the pulley puller from Harbor Freight $10) you can get to it- and a temp solution you can put a cardboard shim in.

This does not apply to 82-83.

Has any Electrical work been done to the car that you can visually see?
My guess would be a short to ground when you activate the horn.
Grab an elecrical diagram from the TSRM and probe around for a problem.
A fuse is either good or blown, it can't be any variable in between.
I don't believe it is an alarm related problem, but never rule that out of th equation.
I only say this because a module is one of the least likely componants in a car to fail.

I've seen with my own eyes a fuse that was partly blown. Still had a connection but was halfway fried. And it was my EFI fuse, right around the same time my fuel pump shat itself.

You may have had a slow blow or "slo-blo" blade type fuse that had started to deform, but didn't open because the high current didn't have enough duration. A blade-type fuse is an insulated soft metal wire that opens a circuit when it reaches it's temperature threshold. It literally vaporizes or melts (depending on fuse style), so it's either working (closed), or blown (open).
In your case, the fuse was still operational, and would have opened the way it was designed to when it was designed to.

What school do you go to?
I used AllData at school a lot, but the info wasn't very helpful on my Supra or Cressida. The mkii Supra TSRM helped me out a great deal more.

In either case, check out the wiring behind your radio. You don't want any mickey mouse wire harness to go up in flames.

re:

Great post, though late in reading this, I can't say how much this helped me with my horn button problem. Thanks for sharing. :)

84's only have 2 horns. The one on the windshield washer tank bracket is only for the factory alarm system.
