horn and cruise control problems
its been almost a year now since these two problems first occurred, but i havent had a need to fix them until now. what happened was when i was driving hove one day with the cruise control on and just in the middle of the drive it cut off and didnt work ever since. i dont know when the horn stopped working, maybe same time, maybe not. i never use my horn so i dont know. i checked the fuses, it isnt the fuses, they're all good. does anyone have a suggestion for me to do to fix it?
sorry if this isnt in the right spot. but it seems more than a general discussion topic. move it if need be.
thanks guys

YOUR FINE...your question is tech related..........for the horn if it is on your 89, more often than not the horn pads on those suckers went bad but it was often due to deteriorated foam and they'd blare all te time, yours doesn't work period so first thing I'd do is go out to the horn itself and have someone push horn button while with a test light you check for power........as for cruise you'll need a wiring diagram and go point to point in the system, it could be as simple as a brake light switch or even a speed sensor down on the tranny but it could be other things to, you'll need the diagram of that system as well and go point to point checking things.

When checking the CC system, what voltage/amperage should I be looking for along the electrical path??? Is it a voltage or nothing, or is there a certain amount of voltage that the sytem needs to work?
Thanks for any help in advance.

there are various components that operate the cruise control, you'll need a description/operation understanding of the system first, some things operate via grounds others current triggered.

You sure it's not the fuses?
The horn on my car used to randomly go off, and get stuck on with the slightest ammount of pressure. So i just took the fuse out for a simple fix.
And since then the CC hasn't worked, i haven't looked into it but i just assumed it was the fuse.

I have experienced the penny issue in the cig lighter as well, and it is covered on tha end. I took the couresty light fuse out, and placed the other fuse there to check the fuse.
When I tap the horn I can hear an electrical clicking sound like a circuit closing. I am leaving here shortly to get a 9 volt battery (I manage to never turn an electrical meter off after using it), but will be testing that when I get back from work.
mjr46, I have been looking for a good diagram of the system, but the only thread I found anything mentioned, the picture was no longer hosted. I know there is a vacuum canister like device in the drivers side fender, but have no understanding of how the system works, other then the VSS sends info to the computer, and the cable on the Throttle body adjusts the speed through more throttle. If you know of a good educational link I would be greatful, as I have no idea how the vacuum plays a role, other the guessing it is measuring the load on the engine somehow....

My wife dropped a penny into her Rav 4 horn button so everytime she turned the damn horn blow.I got a good laugh out of it.

Well, after reading some other threads I found that another issue can be the buttons not making good contact. So I cleaned them a little before going for a battery. On the way back I decided to pull up on the brake pedal and try the CC at the same time, and to my suprise it worked.....
Now I just need to find out how the brake pedal kills the CC and adjust it......
