The turn signal switch activates the signal lights at the rear and front of your vehicle. If the turn signal switch is not working, you might cause accidents and get traffic violation tickets. Fortunately, replacing a faulty turn signal switch is easy. This guide will teach you how you can do it at home.
Difficulty level: Moderate
- New turn signal switch
- Phillips screwdriver
- Ratchet and socket
Step 1. Open your car's hood after making sure that your car is parked in a secure place. Then, disconnect the negative or black battery cable.
Step 2. Remove the lower cover of the dashboard underneath the steering column. Do this with your Phillips screwdriver or ratchet and socket.
Step 3. Using your ratchet and socket, remove the knee bolster under the steering column.
Step 4. So you can remove the upper steering column cover, loosen the bolts attaching the steering column to the support bracket with your ratchet and socket. In some vehicles, the upper cover can be removed once the lower steering column is removed.
Step 5. Loosen the turn signal switch mounting screws with your Phillips screwdriver. Afterwards, unplug the electrical connector switch, and remove the switch from the vehicle. If there are no mounting screws, just pull the switch lever to remove it.
Step 6. Once the switch has been disconnected and removed, replace it with the new switch. Connect the wires and electrical connector in the same way the old switch was connected. If you pulled the switch lever to remove the switch, put it back.
Step 7. Attach the upper cover of the steering column once again, and secure the mounting bolts of the column bracket. Then, install the lower cover and knee bolster back underneath the steering column.
Step 8. Connect the black or negative battery cable, and test your new turn signal switch.
