Where is the horn? - 1999 Chevrolet Cavalier

Disconnect the horn wiring at the horn. Check for voltage at the horn when the horn 'button' is pushed. If there is voltage at the horn, the problem is the horn has died. Remove and replace. No voltage at the horn is most likely related to the horn 'button' but could be wiring. Could also be corroded connections at the horn wiring.
Just had to replace the horn on a 2011 Chevy.
A 1930 Model A horn still works though.

The horn system consists of a single horn, a horn relay located in the underhood fuse block, and driver controlled horn switch in the steering wheel. The horn system is designed to provide the driver with an audible warning to signal pedestrians, other drivers, etc.
Operation
Voltage is supplied to the horn relay coil and contacts at all times through a 10 amp HORN fuse, located in the underhood fuse block. When the driver pushes the horn pad, driver air bag module, the circuit completes and energizes the horn relay coil. This causes the horn relay contact to close. When the contact closes, current travels to the horn and the horn emits an audible warning.

Hi Christian:
Many vehicles have 2 horns so that the sound is more pleasant. If there is no wire connected to a horn, it can not (in my experience) make any sound. May I suggest that you have someone assist you by tapping the horn button while you locate the horn that is sounding.

when pushing on the horn pad you may hear a click noise this tells you the circuit is good from the horn pad to the horn relay and out to the horn. find the horn and check for power at the horn terminal when the horn pad is pushed. if it lights up then replace the horn. if it doesn`t then you will have to check for a wire problem from the horn back to the relay. but horns are usually the problem.

Not being smart but get a manual or youtube it. You need to remember that the air bag is located near the horn device. You can be hurt by the bag if it inflates.

WITH KEY ON EVERY THING ELSE OFF PUSH THE HORN YOU SHOULD HEAR A SMALL CLICK THAT THE HORN RELAY IF SO TEST FOR POWER AT THE HORN MAKE SURE IT IS STILL CONNECTED IF POWER IS GOOD REPLACED HORN

disconnect the horn or horns, operate the horn and see if the fuse still blows. if the fuse still blows then there is most likely a short in the wiring. relays rarely cause shorts. if the fuse doesnt blow with the horn disconnected, reconnect the horn and operate the horn again, if the fuse blows you have a shorted horn.

if you take a test light and test all the fuses in the fuse box and if they are good then when pushing on the horn button you can usually hear the horn relay working(click).if it does then you need to check the horn itself.take a wire and run it from the battery positive cable and connect it to were the horn wire connects to the horn,it should blow(make sure of a good connection),if it does then it could be a dirty connection at the horn.if it doesn`t blow then the horn needs replacing.you can also use the test light and test for power at the horn wire at the horn itself to see if the horn is being feed power from the horn button to the horn.

The dealer can hook up his diagnostic tool and retrieve the fault code. -------------- SECTION 413-06: Horn 2003 Expedition/Navigator Workshop Manual DESCRIPTION AND OPERATION Horn Horn components include the following items:

• clockspring
• horn relay
• horns
• steering wheel pad horn switch

Horn switches The horn switch is incorporated into the driver side air bag module in the steering wheel. The switch is powered through the clockspring and grounded through the steering column. For removal and installation of the horn switch, refer to Section 501-20B .
Horn relay The horn relay is incorperated into the central junction box (CJB). The central junction box is located behind the passenger lower kick panel.

no/ you have 2 horns your right about that but its one wire connector for each horn usually one horn on the right and the other on the left/ the horns should be slide in connector and if he cut them for one doesnt seem right/ I bet that was the problem he tried using the same wire from the original horns when he kind of grounded the horn so it would not work / but there is only one wire per horn/ Please rate my response/ Thank you very much
