A long drive is all we need to shed away the worries and relax our minds. And the ride becomes even more fruitful if your car is working smoothly and perfectly.

Turn Signal Comes On When Brake Is Pressed

Why Does The Turn Signal Come On Hitting The Brakes?

As mentioned earlier, the coming of turn signals is very odd.

#1. Issues in Wiring

This usually happens when there is an underlying problem in the wiring. The brake wire and the wire used to light up the turn signal bulb run close to each other. 

If they intertwine or a cross-connection occurs, then your turn lights might start blinking as you are pressing the brakes. 

#2. The Signal Bulb May Need To Be Changed

Other than that, in some cases, it has also been seen that the problem remains with the turn signal bulb itself. 

The solutions to these problems are also very simple. You need to check the ground wires and locate the ones causing the problems. If you think this is not your cup of tea, take your car to the experts and get it checked thoroughly.

Why Is Blinker Blinking Faster Than Usual?

If you are dealing with a fast blinking light, the brake lights and hazard lights will also malfunction. This usually happens when the brake light bulb of one side or both the sides get burned out. 

If that is not the case, then electrical connection problems in the indicator stalk switch can also make the blinker blink rapidly. Under this circumstance, replacing the brake light bulb will do the job. 

What is a Turn Signal Relay?

Under normal conditions, whenever you hit the turn signal switch, the turn signal will turn on. The component responsible for this is the turn signal or flasher relay. It will keep on getting switched on and off, and you will be able to hear a clicking sound now and then when all the components related to the system are on.

How to Change Your Vehicle’s Turn Signal Switch?

The problem might be lying in the turn signal switch, which acts as an activator to the flasher. It might malfunction whenever you move the signal switch either in an upward or downward direction. You can’t keep the turn signal switch in a malfunctioning condition. But instead of taking it to a mechanic, you can replace the turn signal switch on your own. 

All you need to do is follow the steps mentioned below.

#1. Get a repairing manual

Based on the model and the manufacturer of the car you are using, how you can repair the turn signal switch can vary. So, the first thing you need to do is get a user manual to get all the instructions on how to repair the turn signal switch.

#2. Remove the battery

This is a crucial step in the whole process as not disconnecting the battery from the system will lead to an electrical shortage. Before doing anything, disconnect the negative end of your battery. 

#3. Detach the steering wheel

To reach the turn signal switch, remove the steering wheel from its place. To get the job done, you can take the help of a steering wheel puller. By applying a little force, you would be able to pull the steering wheel off its place. Inside the steering column, you will find a plastic shroud, and by removing that, you can reach the turn signal switch. 

#4. Break the connection with the wiring harness

Before removing the turn signal switch, you need to remove it from the harness with wiring in it. You need to know the sequence to reconnect the wiring harness with the new turn signal switch. Finally, after disconnecting the wires, you will be able to take the turn signal switch out. 

#5. Replace the signal switch

Once the faulty turn signal switch has been taken out, replace it with a new one. Reconnect the wiring harness wires in the same way the old switch was attached to the system. 

#6. Attach the steering wheel again

Now, all the steps will be in reverse. First thing after changing the turn signal switch, you need to put the steering wheel back in its place.

#7. Put the battery back

Now, as you have removed the battery in the beginning, you need to put it where it was to make your vehicle operable again. 

#8. Test the new turn signals

At last, start your car and test whether the whole system is working properly or not.
