My horn unit was rusty and had to be replaced.
Make sure the 1989 Chevrolet Cavalier horn fuse is in working condition. Make sure the positive and ground wires on the horn are tight and free of corrosion.
If the horn on your Chevrolet Cavalier isn't working, it could be due to a few common issues. First, check the fuse related to the horn, as a blown fuse can prevent it from functioning. Additionally, the horn itself may be faulty or there could be a problem with the horn relay or the wiring. Finally, ensure that the horn button in the steering wheel is not malfunctioning, as this can also cause the horn to fail.
under the hood in a fuse box. probably on left inner fender.
the relay or fuse is under the dash board in the drivers side. you will need a flash light but it should be marked on the fuse box. on some of the cavaliers it is not the relay but the positive connection to the horn it self could be coroding. use sandpaper and reconnect.
