Hello. If the lights are staying on then you more than likely have a bad combination switch. The switch fails internally and causes this. It can also be a relay that is staying on, but that is not as common. I would typically use a voltage meter to test the circuits to make sure that the switch is bad. If you are planning on having this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose this.
