Turn Signal Switch
If you can't turn your signal lights on or off while you drive, then you have a big problem. This isn't something that you can just ignore or let pass because this can actually get you into trouble with the law. And even worse, you can get yourself into an accident if you don't address the problem immediately. So, if you think you currently have a faulty turn signal switch in your ride, you'd better replace it right away before it's too late.
Symptoms of a Broken Turn Signal Switch
The symptoms of a faulty switch are not only limited to having problems with your signal lights. You see, most of the electrical components in your vehicle are connected and some vehicles are also equipped with combination or multifunction switches. So, if your switch is not working, other lighting components in your system might get affected as well. Here are some common symptoms that you need to watch out for to determine if you have a busted signal switch.
1. Signal or indicator lights don't work
2. Brake lights don't work
3. Headlights don't work
4. Headlights cannot change from high beam to low beam and vise versa
Turn Signal Switch Troubleshooting and Replacement
If you can't find any physical sign of damage on the switch, you may want to try using some canned air or electrical contact cleaner to troubleshoot the problem first. If cleaning the switch doesn't work, then use an Ohm meter, some test wires, and a 12-volt power source to test the part out. If it still fails, then it's clearly time to get a replacement.
Reminder: Before you begin, don't forget to disconnect the negative battery cable to avoid getting electrocuted during the process. Always follow this safety precaution when working on electrical components in your vehicle.
Step 1: To get the best access, it would be ideal to remove the lower part of the steering column cover. To do this, use the Phillips head screwdriver to unscrew the cover. Once you've removed the screws, you might need to remove several plastic clips before you can take the cover out. For this step, make sure that you don't hit any ignition components to avoid causing further damage.
Step 2: After removing the cover, pull out the flasher that's located at the bottom of the switch.
Step 3: Next, locate the retaining screws of the turn signal switch and use the Phillips head screwdriver to loosen its connection. Then, after the screws have been removed, take the switch out.
Step 4: After that, disconnect the electrical connectors from the switch. You can usually do this by squeezing the bottom tabs of the connectors.
Step 5: Install the new turn signal switch into the steering column and thread its retaining screws using your thumb. If you're satisfied with the placement, tighten its screw using the Phillips head screwdriver. After that, reconnect the electrical connectors and the flasher to the new switch. And finally, reinstall the steering column cover back in place.
