Other times, they work, but only some of the time. This can be frustrating. Before you take your car to the mechanic and spend hundreds of dollars to fix it, see if you can diagnose the problem and fix it yourself.

What a lot of people don’t realize is that your turn signal system is connected to a lot of other systems in your car. For example, your turn signals are connected to the same wirings as your brake lights, warning lights and parking lights.

The turn signal switch is the device near your steering wheel that you use to turn your signals on and off.

However, if it’s something more than that, you need to go see a professional.

Your Bulb Sockets Could Be Oxidized

At some point, almost all parts of your car will suffer from oxidization. This is another fancy word for rust. Things like rust and dust can make your turn signals not work properly.

Your fuse may blow because you have too many signals going at one time. Or, the fuse can actually melt if the energy level gets too high. If your fuse is blown, you will need to replace it.

This module is connected to your fuse through a piece of lead. If this lead breaks or is damaged, it will not work. This isn’t something you can really fix yourself. You’ll need to take it to your local mechanic to get fixed.
