Q: I use my turn signal and my brights come on

Hi and thanks for contacting YourMechanic. Your turn signal and high beams are working on the same switch. If you push the switch up and down, it activates the turn signals. If you move the switch in towards you, it activates the high beams. What happens is the lock inside the switch wears out and makes the contacts to cross when turning on the turn signal. I recommend replacing the turn signal switch on the steering column. If you need assistance having this done, contact a technician, such as one from YourMechanic, to inspect the lights malfunction and replace the switch if necessary.
