Since it’s the job of the turn signal relay to tell the turn signals to turn on, it makes perfect sense that if this component breaks, you’ll lose that feature. #1 – Turn Signal or Hazards Stop Workingīy far the most common symptom of a faulty turn signal relay is that your turn signals or hazards stop working properly. While we’ve highlighted three common symptoms of a bad turn signal relay here, we want to highlight that if your turn signal is blinking too fast, there’s likely causing another issue causing the problem besides the turn signal relay. Below we’ve highlighted three common signs that you might need to replace your turn signal relay. Just because you know where something is and what it does, doesn’t mean you’re ready to jump in and replace it.

Other vehicles (ie: Toyota/Lexus) make it more difficult to get to the relay and may require you to remove a kick panel near your steering wheel. Some vehicles have a guide that will tell you which relay does what right on the fuse box cover, others make you dive into the owner’s manual to find that information. It really depends on which type of vehicle you drive, but on most models, you can find your turn signal relay inside the junction box or the fuse box with your other relays. The turn signal relay is the component you hear when you listen to the clicking sound you hear every time one of these components is on. It’s an electrical component that acts as a relay, and it switches on and off continuously whenever the button is depressed. Your turn signal relay, also known as the flasher relay, is the component that is responsible for your turn signals turning on and off every time you put on a turn signal or hit the hazards. #2 – Turn Signal or Hazards Won’t Turn Off.#1 – Turn Signal or Hazards Stop Working.Let's look at the mechanism that cancels the turn signal when you finish turning. This happens at a rate of one to two times per second. With almost no current passing through the resistor, the spring steel quickly cools, bending back away from the contact and breaking the circuit. This forces the curved spring steel into the contact so that current flows to the signal lights unimpeded by the resistor. At this point, the current is so small that the lights won't even glow dimly.Īfter less than a second, the small piece of spring steel heats up enough that it expands and straightens out the larger, curved piece of spring steel. Current flows through the resistive wire, heating up the smaller piece of spring steel and then continuing on to the turn-signal lights. Initially, the spring steel does not touch the contact, so the only thing that draws power is the resistor. This completes the circuit, allowing current to flow. When you push the turn-signal stalk down, the thermal flasher connects to the turn-signal bulbs by way of the turn-signal switch. A resistive wire wrapped around a smaller piece of spring steel.A piece of gently curved spring steel to which the electrical contact attaches.An electrical contact that conducts electricity into the wire.
