An important aspect of maintaining your vehicle's safety is ensuring all your lights and signaling systems are functioning properly. If you recently replaced your headlights and noticed that your turn signals are not blinking, you might be wondering what went wrong and how to fix it. Here’s how to diagnose and potentially resolve the issue.

Why Your Turn Signal Isn’t Blinking

Replacng your headlights is only one side of the equation. The other critical component is the turn signal, which works in tandem with the headlights. If your turn signal isn't blinking, there are several steps you can take to troubleshoot and potentially fix the problem.

Check the Wattage of the Replacement Bulb

One common issue is that the replacement bulb might not be the correct wattage. If the bulb doesn't draw the necessary current, it won't activate the blinker device. Always make sure the bulb you have is the correct wattage for your vehicle. This is particularly important after a collision, where any damage to the circuit could have affected the bulb's performance.

Check the Year, Make, and Model of Your Vehicle

It's important to note that the location of the turn signals can vary depending on the year, make, and model of your vehicle. For most vehicles, the turn signals are located in the bumper or corner marker lights. However, in older General Motors (GM) vehicles, it's common for the turn signals to not flash if any bulb in the circuit is bad. If you're dealing with an older GM model, it's possible that the collision could have damaged one of the bulbs.

Diagnose the Bulbs and Circuit

First, check whether the replacement bulb is functioning properly. It’s unfortunate, but sometimes even brand-new bulbs can fail or be defective. If the bulb checks out, proceed to check for power at the socket with the four-way flashers or turn signals engaged. If you have power, inspect the plug for any signs of damage. If the plug is undamaged, check the wiring for any visible signs of damage.

Check the Fuses (But Do It Yourself)

While it’s unlikely that a blown fuse is the cause of your problem, it's always worth checking. However, if you suspect a blown fuse, you should be able to check it yourself. If you’re not sure how to do it or feel uncomfortable doing so, it's worth considering a professional diagnosis. After all, many modern vehicles have fuses that are integrated into the body control module, making them less accessible.

Professional Diagnostics and Repair

If you're new to your area and struggling to solve the issue, consider driving to a local repair shop. Professional mechanics have the tools and expertise to diagnose more complex issues. If you're in a remote or unfamiliar area, you might not find a local repair shop that can help.

Safety First

Turn signals are crucial for ensuring the safety of your vehicle and your passengers. Always keep an eye on the status of your signaling systems and have your vehicle checked if you suspect any issues. Driving without functioning turn signals can lead to accidents and put both you and other road users at risk.

Remember, diagnosing and fixing electrical issues in your vehicle can be challenging, especially if you're not familiar with the specific make and model. If you're in doubt, consulting a professional is the safest and most efficient way to resolve the problem.

By following these steps, you can troubleshoot and potentially fix the issue with your turn signals. If you continue to experience problems, consider seeking assistance from a professional mechanic.
