1966-1972 BMW 2000 Horn: A Guide to Replacement and Troubleshooting
Get your classic BMW's horn working again with this guide to common problems and part selection.
- Horn failure on a BMW 2000 is often caused by simple issues like a bad ground, corroded wires, or a faulty relay, not just a dead horn.
- Before buying a new part, test the horn by connecting it directly to a 12V battery.
- Replacement is a very easy DIY job that takes less than an hour with basic tools.
- An aftermarket horn from a brand like Standard Ignition is a reliable and cost-effective solution for this classic vehicle.
Is Your BMW 2000 Horn Failing?
A non-working horn is a common issue on a classic car like the BMW 2000. After decades of use, the original horn can fail due to internal corrosion or electrical issues. Its location behind the front grille exposes it to rain and road debris, which speeds up this process. Often, the problem isn't the horn itself, but other parts of the circuit like a fuse, the relay, or the ground connection.
Common Symptoms of a Bad Horn
- No Sound at All: When you press the horn button, nothing happens. This could be a blown fuse, a bad relay, a wiring issue, or a completely failed horn unit.
- Weak or Muffled Sound: If the horn sounds quiet or "sick," it may be due to corrosion on the electrical connectors, a poor ground connection, or internal failure of the horn itself.
- Intermittent Operation: The horn works sometimes but not others. This often points to a loose wire, a failing relay, or worn contacts in the steering wheel horn button.
Choosing the Right Aftermarket Horn
For a classic vehicle like the BMW 2000, finding a brand new Original Equipment (OEM) horn is nearly impossible. The market primarily consists of New Old Stock (NOS) parts which are rare and expensive, used OEM parts, or new aftermarket replacements.
OEM vs. Aftermarket
Used OEM: A used horn from a donor car can maintain originality but carries the risk of being near the end of its own service life. Prices are generally low.
New Aftermarket: For a functional part like a horn, a new aftermarket unit is often the most practical choice. Brands like Standard Ignition (also known as Standard Motor Products or SMP) produce direct-fit replacement parts that are cost-effective and reliable. While SMP's quality can be inconsistent across their vast catalog, for a simple, universal-style part like a horn for a vintage car, their products are a dependable service replacement.
| Part Type | Price Range |
|---|---|
| New OEM (NOS) | $100 - $200+ (if found) |
| New Aftermarket | $54.41 - $54.41 |
| Used OEM | $25 - $75 |
| Shop Labor | $60 - $120 |
Frequently Asked Questions
Where is the horn located on a 1966-1972 BMW 2000?
The horn is almost always located behind the front "kidney" grilles, mounted to the car's front support panel. This location makes it vulnerable to weather and road spray, which is a common reason for failure.
Is replacing the horn a difficult job?
No, this is a very easy job for a DIY mechanic. It usually involves removing the front grilles for access, unplugging one or two wires, and removing a single mounting bolt. The entire process typically takes less than 30 minutes with basic hand tools. Always disconnect the battery before working on electrical components.
My horn doesn't work. Is it always the horn's fault?
No. Before buying a new horn, it's wise to do some simple troubleshooting. The most common failure points in the system are the fuse, the horn relay, the horn button contacts in the steering wheel, or corroded wiring and grounds. A simple test is to run a wire directly from the battery to the horn's terminals; if it sounds, the problem lies elsewhere in the circuit.
Were there any recalls for the horn on the BMW 2000?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or technical service bulletins (TSBs) related to the horn for the 1966-1972 BMW 2000.
