Cruise control and horn not working

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 Grand Marquis. If both the cruise control and horn aren’t working, and your fuses are good, the most likely culprit is the clockspring inside the steering column. The clockspring is a coil of wiring that maintains the electrical connection to the steering wheel buttons and horn as it turns. When it fails, it can interrupt power to both systems. 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!
