I have a 2000 Town Car and all of a sudden the horn won't honk when I press the control door lock. The horn does work. Its only when I press the lock button. Was wondering if this sounds like it could be the LCM?
The horn operation does indeed route through the LCM. If there is a circuit issue with the LCM controlling the horn we can do a bench test and see what's going on with your unit.I'll include a link for that below. With that being said, there could be a wiring issue going to the horn switch inside the steering wheel that routes through the clock spring assembly so that would need to be inspected as well. https://www.upfix.com/product/lincoln-town-car-1998-2011-light-control-module-lcm-repair/
