Guide to the 1995-2001 GMC Jimmy Hazard Warning Flasher
Having trouble with your turn signals or hazard lights? This guide is for you.
- A failing hazard flasher can cause turn signals to stop working, blink rapidly, or stay on constantly.
- For 2000-2001 models, check for the multifunction switch recall, as its symptoms mimic a bad flasher.
- Location varies by year: 1995-1997 models are under the dash below the radio, while 1998-2001 models are behind the glove box.
- Aftermarket brands like Standard Ignition offer a reliable and affordable replacement for the original part.
Is Your GMC Jimmy's Flasher Failing?
A bad hazard flasher can cause several distinct problems in your 1995-2001 GMC Jimmy. Recognizing these signs early can prevent a safety issue on the road. 🎬 Watch this guide to identify and test common flasher symptoms. The most common symptom is when your turn signals or hazard lights stop working entirely. You might also notice that the lights get stuck in the 'on' position without flashing, or they may not turn off at all. Another clear sign is when the turn signals blink much faster than usual, a condition known as "hyperflashing." This often happens if you've installed LED bulbs, but it can also indicate a failing flasher. In some cases, only one function will fail; for example, the turn signals work, but the hazard lights do not.
Known Issue: Multifunction Switch Recall
For 2000-2001 GMC Jimmy models, General Motors issued a safety recall because the multifunction switch (which includes the hazard switch) could fail. This failure can cause the rear hazard lamps and stop lamps to stop working, increasing the risk of a crash. While the recall focuses on the switch itself, the symptoms can be confused with a failing flasher relay. It's important to verify if your vehicle was affected and if the repair was completed.
Choosing a New Aftermarket Flasher
When replacing the hazard flasher, you don't necessarily need to buy an expensive OEM part from the dealer. Aftermarket brands offer reliable alternatives that meet or exceed original specifications. For the GMC Jimmy, Standard Ignition is a widely available and reputable aftermarket brand.
- Standard Ignition: A well-regarded brand in the aftermarket world, Standard Ignition produces flashers that are a direct fit for the GMC Jimmy. They are known for their quality control and manufacturing standards, providing a dependable and cost-effective solution. Owner reviews are generally positive, citing that the parts work as expected.
Aftermarket parts from brands like Standard Ignition provide a good balance of quality and price, making them a smart choice for most owners.
| Part Type | Estimated Cost |

| New OEM | $40 - $60+ |
| Shop Labor | $60 - $120 |
Replacing the Hazard Flasher
Replacing the flasher is a straightforward job that most owners can do themselves. The difficulty lies in accessing the part.
- For 1995-1997 models: The hazard and turn signal flashers are typically located under the dashboard, below the radio. You will need to remove the lower dash panel (the "knee bar") to get to them, which requires removing several screws. 🎬 See how to access the flasher on 1995-1997 models.
- For 1998-2001 models: The flasher relay is much easier to access. It is located behind the glove box. Simply open the glove box, release the clip to let it drop down fully, and you will see the relay. 🎬 Follow these steps to replace the relay on newer models.
Pro Tip: When you activate your hazard lights, you can often follow the clicking sound to pinpoint the flasher's exact location behind the dash panels.
Frequently Asked Questions
Are the hazard flasher and turn signal flasher the same part?
On many vehicles, including some GMC Jimmy models, they are two separate but identical or very similar parts located near each other. One controls the turn signals, and the other controls the hazards. If your turn signals work but hazards don't (or vice versa), you can sometimes swap them to diagnose the problem.
Why do my turn signals blink fast?
This is called "hyperflashing." It's your vehicle's way of telling you a bulb is burned out. However, it can also happen if the flasher relay is failing or if you have installed LED lights, which draw less power. If all your bulbs are good, the flasher is the next thing to check.
My turn signals don't work when it's cold. What's the problem?
This is an issue some Jimmy and Blazer owners have experienced. It often points to a failing flasher relay or a problem within the multifunction switch. As the components inside the relay or switch wear out, temperature changes can affect their ability to make proper contact until the vehicle's interior warms up.
Can a bad flasher drain my battery?
Yes. If the flasher relay gets stuck in the "on" position, it can keep the circuit active and the lights illuminated, which will drain your battery if the vehicle is turned off.
