Ford Bronco Turn Signal Switch Guide for 1985-1996 Models
Having trouble with your turn signals not working or canceling? Here’s what you need to know before you replace the switch.
- The most common failure is the turn signal not canceling due to a broken internal plastic cam.
- Many cheap aftermarket switches fail quickly; consider spending more for a premium brand like Standard Ignition or finding a used OEM part for better durability.
- If your hazard lights work but turn signals don't, the switch is a likely culprit after you've checked the flasher relay.
- Replacement is a DIY-friendly job but requires a steering wheel puller and careful handling of the wiring harness.
Common Failure Symptoms in 1985-1996 Broncos
The turn signal switch in these classic Broncos is a high-use part, and its internal components, often made of plastic, can wear out or become brittle over time. Knowing the signs of failure can help you diagnose the problem correctly before you start buying parts.
| Symptom | Description |
|---|---|
| Turn Signals Don't Cancel | This is the most common complaint among Bronco owners. After you make a turn, the signal stalk doesn't return to the neutral position. This is almost always caused by the small plastic canceling cam inside the switch breaking. These plastic parts become brittle with age and snap. |
| Signals Don't Work at All | If neither turn signal activates, the problem could be the switch, but you should first check the fuse and the flasher unit. If the hazard lights work but the turn signals don't, it points more strongly to a bad turn signal switch, as they often use separate flasher relays. |
| Signals Only Work When Holding the Lever | If the blinkers only flash when you physically hold the lever in position, it indicates worn electrical contacts inside the switch assembly. The internal mechanism that should lock the lever in place has failed. |
| Other Electrical Issues | Since this is a multi-function switch, failure can also affect other systems. Problems with wipers not parking correctly or issues with high beams can sometimes be traced back to this switch. |
Known Issues: OEM vs. Aftermarket Quality
For this generation of Bronco, there's a noticeable difference in quality between original Ford parts and many aftermarket options. Forum discussions with long-time owners reveal a common frustration: cheap aftermarket turn signal switches often fail quickly. Some owners report replacing an aftermarket switch multiple times in just a few years, with the plastic canceling cams being the primary point of failure. One owner noted that an aftermarket part lasted only about a month before breaking.
Aftermarket switches, especially budget-friendly ones, are known to use more brittle plastic for the canceling cams compared to the original factory parts. This makes them prone to breaking, particularly in cold weather or when used with an aftermarket steering wheel hub that may not align perfectly.
Choosing the Right Aftermarket Switch
When your original switch fails, you'll have to choose from available aftermarket brands. They generally fall into different quality tiers.
- Premium Aftermarket (e.g., Standard Ignition): Brands like Standard Motor Products (SMP) are often considered a higher-quality aftermarket choice. Owners in forums have had better luck with these, though they come at a higher price. They are engineered to meet or exceed original specifications and undergo testing for performance.
- Standard/Value (e.g., Rostra, Skyward): These brands offer a balance of price and quality. They are designed as direct-fit replacements to restore original functionality. While there is less specific feedback on these brands for the Bronco, they are established aftermarket manufacturers.
- Budget (e.g., Replacement): These are the most affordable options and are popular with DIYers looking for a quick, low-cost fix. However, be aware that this is the category of parts most frequently criticized in owner forums for premature failure. You might be replacing it again sooner than you'd like.
Pro Tip: If your original switch is still partially functional and only the canceling cam is broken, it's sometimes possible to just replace the cam itself. 🎬 Watch: How to replace the turn signal cam on tilt columns Some owners also go to junkyards to find an original Ford factory switch, which they find to be more durable than new, cheap aftermarket parts.

Frequently Asked Questions (FAQ)
Is replacing the turn signal switch a DIY job?
Yes, for someone with moderate mechanical skill. The replacement involves removing the steering wheel and the plastic covers on the steering column. You will need a steering wheel puller tool. 🎬 Watch: A detailed walkthrough of the removal and installation process The most difficult part for many is feeding the new wiring harness down the steering column and correctly pinning the new wires into the connector if the new switch requires it. The job typically takes about 1-2 hours.
Are there any recalls on the 1985-1996 Bronco turn signal switch?
No, there are no specific recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for the turn signal switch on the 1985-1996 Ford Bronco. Searches show recalls for much newer Bronco models, but they do not apply to this generation.
My turn signals blink fast. Is that the switch?
A fast-blinking signal (hyper-flash) is almost always caused by a burned-out bulb somewhere in the system, not the switch itself. The reduced electrical load makes the flasher relay cycle faster. Before replacing the switch, check all your front and rear turn signal bulbs.
Why do my hazard lights work but not my turn signals?
This is a classic symptom of a failed turn signal switch or a bad turn signal flasher relay. In many Ford trucks of this era, the hazard lights and turn signals use separate flasher units. Since the hazards work, you know the bulbs are good. The problem lies within the turn signal circuit, with the switch being a very common culprit.
