For 1990-2009 cars

The HAZARD fuse applies voltage to the horn relay. The horn relay coil is grounded when either of the following switches are closed:

• | The left side horn switch

• | The right side horn switch

Then the following actions occur:

1. The horn relay energizes.
2. The contacts close.
3. The horn receives voltage.

The horn is permanently grounded at G102. The horn sounds until you release both the left side and the right side horn switches.
