1992-1993 GMC Typhoon Turn Signal Switch Guide
Having trouble with your turn signals, wipers, or high beams? Your multifunction switch is likely the problem.
- The turn signal switch in the Typhoon is a multifunction unit controlling signals, wipers, and high beams.
- Failure is common and can cause signal, wiper, or headlight issues.
- Before replacing the switch, check fuses, bulbs, and the flasher relay first.
- Aftermarket brands like Standard Ignition offer a quality replacement, as OEM parts are rare.
Is Your Turn Signal Switch Failing?
A bad turn signal switch in your GMC Typhoon can cause more than just an annoying clicking sound. Because it controls multiple systems, you might notice a few different problems. Being aware of these symptoms can help you pinpoint the issue before it becomes a serious safety hazard.
Symptoms of a Bad Turn Signal Switch
The turn signal switch in your Typhoon is a hard-working part. After decades of use, failure is common. Here are the signs that your switch may need to be replaced:
- Turn Signals Don't Work: The most obvious sign is when your turn signals don't activate at all, on one or both sides. This could be a switch failure, but it's wise to first check for simpler issues like a blown fuse 🎬 Watch this guide to diagnose why your turn signals aren't working. or burned-out bulbs.
- Signals Don't Cancel: The switch has a mechanism that should automatically turn the signal off after you complete a turn. If you have to manually turn it off every time, the switch is worn out.
- Signals Only Work When Holding the Lever: If the blinker only stays on while you're physically holding the lever in place, the internal locking mechanism has likely failed.
- Hazard Lights Malfunction: A faulty switch can cause the hazard lights to not work or, in some GM vehicles, to come on unexpectedly when you use a turn signal.
- Wiper or High Beam Issues: Since this is a multifunction switch, you might also experience problems with your windshield wipers or the ability to switch between high and low beams.
Check for Simple Fixes First
Before condemning the switch, always check the basics. A rapidly blinking signal usually means a bulb is out. If no signals work, check the turn signal fuse and the flasher unit. 🎬 Learn how to replace a faulty GM directional relay. Sometimes, electrical issues that seem related to the switch are actually caused by a bad ground connection at one of the light bulbs.
Choosing the Right Aftermarket Switch
For a specialty vehicle like the Typhoon, finding an original GM (OEM) part can be difficult and expensive. Aftermarket parts are a reliable and affordable alternative. The key is to choose a quality brand. The turn signal switch for the Typhoon is shared with other popular GM trucks from that era, like the S-15 Jimmy, which means aftermarket support is good.

Frequently Asked Questions
Can I replace the turn signal switch myself?
Yes, this is a DIY-feasible job for someone with moderate mechanical skill. However, it requires special tools, including a steering wheel puller and a lock plate compressor tool. The process involves removing the steering wheel to access the switch inside the column, which can be tricky.
Are there any recalls for the GMC Typhoon turn signal switch?
There are no specific recalls for the turn signal switch on the 1992-1993 GMC Typhoon. A recall for a similar issue on other GM SUVs (NHTSA Recall No. 01V364) affected later models but highlights that switch failure is a known problem on these platforms.
What's the difference between a turn signal switch and a flasher relay?
The turn signal switch is the lever on your steering column that you operate. The flasher relay is a small electronic component, usually located under the dashboard, that makes the lights blink on and off. If your signals light up but don't blink, the flasher is often the problem. If they don't light up at all, the switch could be the cause.
Why do my brake lights or wipers have problems if the turn signal switch is bad?
This is because it's a 'multifunction' switch. The wiring for the turn signals, brake lights, hazard lights, and wipers all passes through this single component. A fault inside the switch can interrupt the electrical circuit for any of these other systems.
