SOURCE: security system/battery

plz check the following and update me
1. Fuel (To be exact proper air/fuel ratio, normally it is about 14/1)
2. Spark (in appropriate moment)
3. Proper timing (the valves should open and close only in appropriate time)
4. Compression in the cylinders (Normal compression is 120 - 170 psi. The engine won't start if the compression is lower than 70 - 80 psi.)

SOURCE: The Horn

This sounds like it could be damaged wiring in the steering column. Would suggest a qualified repai shop, especially if the vehicle is equipped with an airbag.

SOURCE: windshield wiper turns on when car starts, then won't stop

The van is now about 13-14 years old, chances are that the switch has worn to a point that the finite metal particles are shorting it out causing it to be on all the time. Re and clean the switch contacts, you should be good to go. Please let me know how you make out. Good luck..

SOURCE: 2003 Hyundai Tiburon. The horn will start blowing

There are a few possibilities:

First of all, don't use the factory alarm. If the problem disappears, then the alarm is causing the horn to activate.

If that doesn't help, then verify the horn switch itself. Probably best to have your dealer do this because it's very close to the airbag.

If it's not that, then it may be the dreaded BCM starting to fail. The BCM, or "Body Control Module" is a dealer only component.

What would cause the horn of a car to go off unexpectedly?

a horn pad problem on the steering wheel can cause this but its rare to happen on any Mazda car. a horn relay that has shorted out will cause this to happen. you will have to find the relay and pull it out the horn will stop.

Horn sticking and sounding on 2005 ford f150

The button or wire is shorted in the column. Horn relays turn on with a ground signal from the button, so the wire only has to come loose or the wire get chaffed to cause the horn to blow.

The horn is stuck on my 2001 mirage. as soon as i ture the ignition, the horn starts blasting nonstop. please help

This would be caused by one of two things, first check the horn pad and make sure the horn button (pad) is not broke or stuck if thats okay then i would replace the horn relay, this relay is located in the fuse box, also check the under the hood fuse box. they started putting the horn relays in the engine compartment fuse/relay box, the cover of the fuse box will list where the relay sits in the box. good luck, hope this helps.
