Common Ford Explorer Turn Signal Assembly Problems and Their Causes
Some countries in the Southeast Asian region are known for having drivers who use their hands and feet to warn other drivers of the direction their vehicles will take. Fortunately, you wouldn't have to use your limbs as signals because your Ford Explorer is equipped with a reliable turn signal assembly. The bad news is that no matter how efficient your vehicle's turn signals are, they will eventually deteriorate and fail at some point. But don't fret! You can actually troubleshoot turn signal assembly problems before they become totally worse. Here are the most common signs of Ford Explorer turn signal assembly failure that you need to watch out for:
Foggy turn signals
Does your turn signal assembly's light beam seem darker than usual? This may be a sign that your turn signals are becoming cloudy or hazy. Many factors can cause this turn signal assembly problem, and one of them is a faulty light bulb. If your Ford Explorer turn signal assembly uses a regular halogen bulb, it has a higher probability of failing after just one year. Since a halogen bulb produces more heat compared to other light sources, its life span is relatively shorter. If you already checked your turn signal's bulb and it turned out to be fine, you may want to check its attachment to the socket. Sometimes, a loose bulb can also make the turn signal's light beam fade. In this case, tightening the bulb in place is enough to solve the problem. But for a damaged light bulb, replacement is the only solution. Another possible cause is your vehicle's turn signal cover or lens. Because it is usually made of plastic, the turn signal lens tends to become yellowish after some time. Its dinginess is often caused by heat, humidity, and salt from the environment. You can remove this cloudy layer using the restoration kits sold online. But if you have the resources, you can opt to replace the turn signal cover.
Abnormal blink rate
It is normal for your vehicle's turn signals to blink. However, if the blinking becomes too fast, too slow, or if there's no blinking at all, your turn signal assembly's flasher might be in trouble. A burnt or blown-up fuse as well as a busted relay can cause the flasher to malfunction. In this case, you can just replace these broken parts to solve the problem. But if all these components are working properly, the flasher itself might be the problem. When a flasher goes bad, the only option is to replace it. Replacement flashers for your vehicle's turn signal assembly are actually cheap. Plus, they are very easy to install. The process of removing the old unit and installing the new one will only take an hour or less to finish.
Other troubleshooting tips
If your Ford Explorer turn signal assembly is not working, you may also inspect the other turn signal assembly parts for damage. These include the switch, bulb sockets, and wiring harness. You also need to check the main source of power, which is the battery, just to make sure that it is supplying enough electricity to make the turn signals work.
