Horn won't stop blowing on my buick century 2001 after I reconnected the battery?

well on most cars now it can be. this.
1: bad relay.
2: bad horn button
3; bad clock spring.
4: bad wring to relay.

we use tool called a voltmeter to find this, easy
lacking tools all you can do is look and guess.
or got to any shop and get if fixed, pull the relay first and go.

if all else fails get an air horn and blow it at the same time the horn gets pressed to make the inspector think it works. ;)
Try popping the hood on your car and look for the horn. They should be up near the front by the radiator or headlights then take the connections off and replace them securely. If no luck there replace the fuse, the fuses dont always look blown when they stop functioning. After that take the horns out of your car (usually just a screw to dismount the bracket holding the two horns to the panel.) and manually hook power up to them by touching wires to the ports and then power on the wire. (i know that we allways make sure there isnt power to the wire before we need there to be there because its just not safe...right?) At this point you should know your problem. If not than you need to test your power leading into your horn.

the horn work?
connections from the battery terminals are clean?
If so, remove the battery terminals for up to 5 min and fit back
Now try to start the car!

The easy way is to locate the horn under the hood of your car and reconnect the wires to the horn

If you look at the key you should see a back plastic piece with a little metal strip in it try to clean it with alchol. it is a resistor that tells the car it has the right key

possible horn itself is faulty and needs replacing. you will need to locate where the horn is and apply power to the horn from the battery. if the horn sounds then you know that it is a broken wire th=o the horn

you need to change the blower. It is located under the dash on passenger side. Cost used $50.00

Change the thermostat under the intake horn.

check your fuses
