Common problems with a Lincoln horn are that it just quits working. Another common issue with the horn is that it will continuously blow whether the car is on or not.
If a Lincoln Town Car's horn whirls then the horn is broken and will need to be replaced. The horn is located in the bumper towards the front of the car.
The most common horn problems are either a blown fuse or a bad horn relay. Both should be located under the hood in the fuse box.
