Uchanics reports that the average cost of replacing a car horn typically ranges from $80 to $200 for parts and labor combined. They emphasize that while replacing a horn is generally straightforward, diagnosing the problem can sometimes reveal additional issues that may increase costs.

Why Car Horns Fail and Require Repair

There are several common reasons car horns malfunction and require repair:

Faulty Electrical System – Issues with wiring, fuses, or relays that power the horn are a prime culprit. Shorts or loose connections can cause intermittent or no sound.

Damaged Horn Unit – The horn mechanism itself may become cracked or corroded. This leads to weak, distorted sound.

Broken Horn Button/Switch – If the button on your steering wheel has issues, the horn won’t activate even if operating normally.

Blown Fuse – Like any electrical component, the horn relies on a fuse. A blown fuse cuts power and disables the horn.

Broken Relay – Relays help switch horn power on. A damaged relay prevents proper operation.

Let’s look at what’s involved in fixing these issues.

Car Horn Repair Cost Factors

Several variables sway the total charges for fixing or replacing a faulty car horn system:

Labor Rates and Shop Fees – Like most auto repairs, regional labor rates significantly influence the final price. Complex diagnoses or accessibility issues take more work hours.

Make and Model of Vehicle – More premium brand cars often have higher list prices for OEM parts and more complex designs overall.

Horn Type – Larger air horn systems cost more than basic OEM horns to repair.

Extent of Electrical Diagnosis – If wiring or embedded electrical issues cause the malfunction, costs climb due to lengthier troubleshooting.

Horn Location and Accessibility – Horns positioned awkwardly behind bumpers or grilles take longer to service, increasing labor time.

Parts Requiring Replacement – Whether the horn, fuse, relay, button, or wiring components need replacing affects parts costs.

OEM vs Aftermarket Parts – Genuine OEM components are often pricier than third-party replacements.
