Why Is My turn Signal Blinking Faster?

Turn signals play a crucial role facilitating communication between drivers. Historically, drivers relied on hand signals to indicate their intentions, a practice that has largely been replaced by modern signaling systems. A properly turn signal typically blinks at a rate of 60 to 120 times per minute. However, as components wear down or fail, you may notice changes in the blinking speed or sound. Fortunately, due to the similarities in turn signal circuitry across most vehicles, a trained technician can quickly diagnose any issues and restore your signaling system to optimal.

REASONS WHY YOUR TURN SIGNAL IS BLINKING FAST

A Failing Bulb

The most common cause of an improperly blinking turn signal is the bulb. When you turn your blinker on, electricity runs through a fuse in the fuse box to the turn signal circuit. It then activates and sends power to a secondary load circuit that’s connected to your blinker’s lightbulb. If the bulb is faulty, it alters the resistance in the circuit, making it blink erratically. You can test each turn signal to see if they are illuminating properly. Check the bulb for darkness, cloudiness, or a broken filament. If you notice a difference in your blinker, you’ll most likely need a new bulb, which a service provider such as AAA Million Auto Parts has.

Poor or Damaged Electrical Connections

An improper electrical connection anywhere in the circuit—whether it involves the power or ground connection—can significantly disrupt the current flow. A poor ground connection, for instance, can introduce resistance into the turn signal circuit, depriving the blinkers of power and causing them to either dim or blink inconsistently.

Additionally, issues with a malfunctioning electrical switch can affect the resistance or blinking rate of your turn signals. Corrosion, worn insulation, or even burns on the switch may result from such faults. Similarly, degraded relays and flashers can create a poor connection to the blinker system. The clicking sound you hear when activating the blinker originates from the turn signal relay or flasher, so it’s important to listen for any unusual clicking noises as an early indicator of potential issues.

HOW TO CORRECT A FAST BLINKING TURN SIGNAL

University Name

Today’s cars have many complex design features that make it trickier for you to correct issues yourself. Come to AAA Million Auto Parts, we will help save you time in determining what electrical issues your car may have. But if you’re a Do-It-Yourselfer (DIYer), there are a few steps you can take to determine what the blinker issue may be.

Check all wiring for any damage or wear and tear. Clean the turn signal components and the surrounding areas. Check your fuses to make sure they’re all working. Test your car’s battery to see if it’s underperforming. Replace your blinker bulbs if your car light is out.

HOW TO REPLACE YOUR BULB

Replacing the blinker bulb in most cars is relatively easy. But if you don’t feel 100% confident in doing it yourself, just bring your car to AAA Million Auto Parts to complete the service for you. If you decide to replace it yourself, follow these easy steps:

Open your hood and locate the area your blinker is housed in (depending on your vehicle you may need to unscrew the mounting screws to remove the headlamp or turn signal housing before replacing the bulb).
Remove the electrical connector by pushing down and then back on the locking tab.
Remove the defective bulb by turning it counterclockwise (you may need to pull the bulb straight out or push the bulb inwards while turning).
Install the new bulb (be careful not touch the new bulb’s glass because the oil from your fingers can cause the bulb to fail prematurely). If the bulb has alignment pins on the bottom, ensure they align with the corresponding openings.
Reconnect the electrical connections and replace the housing if necessary.
Turn on your vehicle and test the turn signal to ensure the replacement bulb is working

WORKING BLINKERS = SAFER DRIVERS

Properly working turn signals are a vital part of safe driving. A nonfunctioning blinker can not only put you in danger, but also endanger other drivers. And in some states a damaged blinker can earn you a traffic violation. So, if your turn signal starts blinking fast, head over to AAA Million Auto Parts where we will help ensure that your car’s lighting/electrical systems are meeting or exceeding your vehicle’s Original Equipment Manufacturer’s (OEM) standards.
