If your turn signals don’t work at all, the turn signal switch may be faulty. Of course, the problem has many other potential causes as well, so you’ll want to do some troubleshooting before condemning the switch.

Where is the turn signal switch on a car?

The turn signal switch is a lever usually mounted on the steering column used to signal other drivers when turning right or left. A turn signal switch should last the life of the vehicle. However, there are instances where the switch may fail because of manufacturing defects, rough use, or other reasons.

How does a computer control a turn signal?

Meanwhile, on newer vehicles, a computer, which is often referred to as the body control module (BCM), manages the turn signals. When the driver operates the turn signals, an electrical signal is sent to the body control module (BCM). The latter then activates (or tells another module to activate) the turn signal lights and perform flashing duties.

What causes the flasher on a turn signal switch to flash?

The flasher contains a switch that opens and closes the circuit to the turn signal switch, causing the turn signals to flash when activated. The flasher is also responsible for the clicking noise you hear when activating the turn signals.

The good news is that all of these symptoms point to two possible issues, a bad turn signal relay or a dead bulb. If the signal blinks really fast, you have a bulb out on that side. If it doesn’t come on at all or doesn’t blink, you’ll need to replace your turn signal relay.

A turn signal switch should last the life of the vehicle. However, there are instances where the switch may fail because of manufacturing defects, rough use, or other reasons. If your turn signals don’t work at all, the turn signal switch may be faulty.

How does a turn signal light relay work?

The majority of turn signal lights are controlled by a flasher. This flasher is also known as a relay that is a part of the electrical system. This system controls when the light will flash on and off. So, how exactly does this work?

How can I tell if my turn signal relay is failing?

Other Lights Start Failing: Another common sign of a failing turn signal relay is all of your lights start failing. Sometimes your headlights, brake lights, or running lights will start to malfunction. This is correlated with your turn signal relay.

Why is my left turn signal not working?

However now the left turn signal is just not working. Right works completely fine, and the 4 ways, which are 2 ways right now, work as they should. After some digging, most routes pointed to the turn/flasher module, GM part # 15764135.

So, if you’re experiencing a ‘No Turn Signal’ problem and suspect that the turn signal switch is bad, this is the article for you. You’ll be able to specifically test the following: No Front Left Turn Signals. No Rear Left Turn Signals.

What are the numbers on the turn signal switch?

One more very important thing: If you disconnect the turn signal switch’s connectors, you’ll notice that: The Gray connector has the numbers 1 through 13 embossed on one side. The Black connector has the numbers 1 through 17 embossed on one side.

What happens when the turn signal switch is false?

The purpose of direction signal system is to operate with a flasher or blinker unit which interrupts the signal which caused the blinking action. When a turn signal switch is false, the system will short or go “open” leading the blinker not to operate. Then, you use the test light to test input and output power circuits.

Check for a blown circuit fuse. Verify that circuit connections are not loose, corroded or unplugged. Inspect the wiring harness or terminals for the rear section of the circuit. Check for a bad connection between the turn signal switch and the flasher or between the flasher and the ignition switch.

How can I tell if my turn signal switch is working?

However, if the flasher unit is working fine, check the fuse. Also, check for a bad connection at the turn signal switch or an open in the part of the circuit that connects the flasher unit to the turn signal switch. See the section ‘Checking the Turn Signal Switch.’
