What would cause the left side parking lights to stay on

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Milan. It sounds like there could be an issue with the parking light circuit, possibly a faulty relay or a malfunctioning switch. Sometimes, the parking light switch can become worn or damaged, causing the lights to stay on. It could also be an issue with the body control module (BCM), which controls the lighting system. Additionally, a short in the wiring could be keeping the lights on. It's best to have the system inspected to determine the exact cause and fix it properly. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
