What is a little yellow light that comes on , on the dashboard

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your Town and Country. The little yellow light you're describing sounds like a warning light. It could be for anything from low tire pressure to a maintenance reminder. Your vehicle's manual can help identify the exact warning. Given that it dings when you start the car and stays on, it may be a good idea to have it checked out. 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. Give us a call at 877-913-1554, and we will happily help you out!
