Horn not working chevy malibu

fuse for horn on a 2001 malibu is located under the hood.
there is a fuse (15 amp) in slot #43
and there is a relay in slot #21
if you remove the relay and put it back in wrong the horn will not work.

The only way to check it correctly is with a test light, And have someone hit the horn while you watch the test light to work, But it will probably be the horn itself.

You would need to check the circuits at the relay.
The horn pad grounds the relay to make the horn blow.
You should have power at the relay, and a ground from the horn pad when it is pressed. The third wire goes to the horns.

If your not going to fix the horn plate in the column. Wiring a horn button is easy. You need a hot lead from the fuse panel to the after market button and from the other side to the horn button under the hood unit (grill area). Most horn unit are self grounding.

If its like my 99 Chevy Lumina, its behind the front bumper, passenger side. You'll have to take the whole front bumper off. Stupid I know. But thats how Chevy made them.

under the hood or under the dash

No the Chevy Malibu is not made by Kia!
I think you mean horn relay
I would try a new relay it is possible that the relay is defective and that's why it was removed
here is how the horn circuit works
The body control module (BCM) controls the horn relay by grounding the control circuit of the horn relay coil. When the horn relay coil is grounded, the horn relay contacts close, applying voltage to the horn via the horn supply voltage circuit.
if the horn relay does not fix your concern you may need to take it to a shop and check for any BCM fault codes
and you are correct having no horn is a SAFETY ISSUE
that car should have NEVER PASSED A SAFETY WITHOUT A HORN
hope this helps good luck and I hope the relay fixs it because a BCM is costly

It should be a T-30.

sound like horn pad is bad.you going to have to replace horn pad and air bag as a whole unit.horn and air bag is all in one.this is a dealership fix.

Hi. If your airbag has not deployed, you don't have to replace it. The airbag may have to be removed to get at the horn circuit. Try taking it to an independent auto repair place. I'll be willing to bet that they'll give you a better price for the repair. Good luck! ricardok45
