FAQs
Q: My turn signals aren’t working at all. What could be the problem?
A: The most common cause of turn signal failure is a blown fuse. Check your owner’s manual to locate your vehicle’s fuse box and check for a blown turn signal fuse. If the fuse is fine, it’s possible that your turn signal switch or flasher unit is faulty and needs to be replaced.
Q: My turn signals are flashing too fast. What could be the problem?

Q: My turn signals work, but they don’t light up. What could be the problem?
A: If your turn signals work but don’t light up, it’s likely that the bulbs are burnt out. Check all of the bulbs and replace any that are burnt out.
Q: My turn signals work intermittently. What could be the problem?
A: If your turn signals work intermittently, it’s likely that there’s a loose connection somewhere in the system. Check all of the connections and make sure they’re tight. If this doesn’t solve the problem, you may need to replace your turn signal switch or flasher unit.
Q: How can I prevent turn signal problems in the future?
A: The best way to prevent turn signal problems is to perform regular maintenance on your vehicle. Check your bulbs and connections regularly, and replace any faulty components as soon as possible.
