Used horn (horn) with bracket to the bodywork for Citroën C4 cars of the first generation. This is an original part from the PSA concern, suitable as a spare part in the event of a loss of horn sound, a weak tone or mechanical damage to the original horn. Thanks to the retained bracket, mounting back on the body is significantly easier.

Manufacturer: PSA / Citroën / Peugeot
Model: Citroën C4 I (first generation)
Product codes: 6236G4
Other numbers: often searched also as 6236 G4, PSA 6236G4

This horn is especially suitable for car mechanics and home-builders who are looking for a cost-effective and at the same time original solution to the malfunction of the sound warning device. Compared to universal horns, it offers the correct fit, adequate sound and compatibility with the electrics of the Citroën C4.

The horn is designed to be mounted in the original place in the front part of the vehicle, on the body using the included holder. Before installation, we recommend checking the condition of the electrical connector, cleaning the contacts and verifying that the supply cable is not damaged. In older cars, oxidation of the contacts or a loose holder is a common problem, which can affect the function and volume of the horn.

Installation recommendations:
– Always disconnect the battery before working to avoid a short circuit when handling the wiring.
– Check the attachment of the bracket and the tightening of the screws, the horn must be firmly attached to the body for proper grounding.
– Before finally tightening the screws, briefly test the horn to see if it sounds correctly.
– Pay attention to the correct position of the horn (water drainage downwards) so that it does not flow into it and prolongs its service life.
– During installation, do not twist the wiring and prevent the wires from coming into contact with sharp edges or moving parts.

This part is the ideal choice in a situation where you need to quickly and economically restore the full function of the horn on a Citroën C4, while maintaining the quality and characteristics of the original PSA part. With the exact part number 6236G4, it is easy to locate and compare with the original piece removed from the vehicle.

This electric horn (part number 6236G3) is a direct-fit replacement designed for Citroën C4 owners and professional mechanics looking for a reliable restoration of audible warning function. The unit includes the mounting bracket for attachment to the body and matches OE mounting points and electrical connector layout in most original installations. Robust construction ensures clear, loud tone required for safe road use while keeping installation straightforward for workshops and competent DIY technicians.

Technical Information

Manufacturer: Stellantis (Citroën / Peugeot)
Model: Citroën C4 (First Generation)
Product Codes: 6236G3
Additional Numbers: 6236.G3, 6236G3/6236.G3

Function

The horn produces an audible warning signal to alert other road users. It operates from the vehicle 12 V supply via the horn relay and switch on the steering column. Proper function depends on the horn diaphragm, internal contacts and a good ground connection.

Typical Failure Modes

Horns are durable but commonly fail due to:

• Corrosion and water ingress causing poor contact or seizure of the diaphragm.
• Mechanical damage from impacts or road debris that deform the horn or bracket.
• Electrical faults such as blown fuses, failed relay, loose ground or damaged wiring.
• Fatigue of internal components after many years of service, reducing sound output.

Installation Recommendations

Before starting, always disconnect the battery to avoid short circuits. Locate the horn behind the front grille or near the radiator support depending on vehicle version. Remove the retaining bolt and unplug the electrical connector. Fit the replacement horn with the supplied bracket to the original mounting point, connect the connector, and secure all fasteners. Reconnect the battery and verify operation using the horn button; if the horn does not sound, check fuse, relay and ground connection before further disassembly. Tighten fasteners to manufacturer recommendations and avoid bending or touching the horn diaphragm when handling.

Notes for Mechanics and DIY Enthusiasts

Part number 6236G3 is frequently used as a search term, so include it when sourcing or checking compatibility. When replacing the horn, inspect the relay, fuse and wiring harness to eliminate related electrical causes. If the mounting bracket shows corrosion or cracks, replace or reinforce it to prevent future misalignment and noise issues.
