Subaru GL-10 Horn Replacement and Upgrade Guide (1987)
Restore this critical safety feature on your 1987 Subaru GL-10 with a reliable new aftermarket horn.
- A non-working horn is a safety issue and can cause you to fail a vehicle inspection.
- Always check the fuse first, as it's a simple and inexpensive fix.
- Replacement is very DIY-friendly, requiring only basic tools and less than an hour of your time.
- Aftermarket brands like Standard Ignition and Replacement offer reliable and affordable options, as OEM parts are scarce.
Is Your Horn Failing? Common Symptoms
A failing horn on your GL-10 will be obvious, but the cause might not be. Before you replace the horn itself, it's a good idea to check a few other things first. A common point of failure in many cars is the fuse or the horn relay. On some older Subarus, the horn is tied to the same fuse as the hazard lights and clock. If those are also out, your problem is likely a blown fuse.
Common symptoms of a bad horn include:
- No Sound: The most common symptom. You press the horn button and nothing happens. This could be the horn itself, the fuse, the relay, or the wiring.
- Weak or Quiet Sound: If the horn sounds muffled or much quieter than it used to, the horn unit itself is likely failing internally.
- Intermittent Operation: Sometimes it works, sometimes it doesn't. This often points to a loose connection, a failing relay, or a problem in the steering column's wiring, sometimes called a clock spring.
Pro Tip: Check the Fuse First
Always check the fuse box before buying a new horn. A simple blown fuse is a much cheaper and easier fix. In some GL/DL models, this fuse also powers the hazard lights and clock, giving you a quick way to diagnose the issue.
Choosing the Right Aftermarket Horn
Finding a new original equipment (OEM) horn for a 1987 vehicle is nearly impossible. Thankfully, the aftermarket offers several reliable, direct-fit options that will get your GL-10's horn working again. The horns available are typically universal or semi-universal 12-volt electric horns that are easy to install.
Brand Tiers
- Standard Ignition: A well-regarded aftermarket brand that produces parts designed to meet or exceed original factory specifications. A Standard Ignition horn is a solid choice for a reliable, long-lasting replacement that functions like the original.
- Replacement: This brand offers a cost-effective solution. If you're on a budget and need a functional horn to pass a safety inspection or simply restore the feature, a Replacement-brand part will do the job effectively.

Frequently Asked Questions (FAQ)
Where is the horn located on a 1987 Subaru GL-10?
On most cars from this era, including the Subaru GL/DL line, the horn or horns are located behind the front grille, mounted to the radiator support or a nearby bracket. This position allows the sound to travel forward without being muffled by other components.
Is replacing the horn a difficult job?
No, this is a very easy job suitable for a beginner. It typically involves removing the front grille for access, unplugging the electrical connector, and unbolting the old horn. The new horn bolts in its place, and you simply reconnect the wire. The entire process usually takes less than an hour with basic hand tools.
My new horn doesn't work either. What else could be wrong?
If a new horn and a good fuse don't solve the problem, the issue could be the horn relay, the horn button in the steering wheel, or the wiring in between. A common failure point in the steering column is the 'clock spring,' a coiled wire that allows the steering wheel to turn while maintaining electrical contact. If the horn only works when the wheel is turned to a certain position, the clock spring is the likely culprit.
Will an aftermarket horn sound different from the original?
It might sound slightly different. Aftermarket horns are designed to produce a standard, effective tone, but it may not be an exact match to the 1987 factory sound. Some vehicles use a high-note and a low-note horn together for a fuller sound; your GL-10 may have one or two. Replacing a single failed horn might result in a slightly different pitch than you're used to.
