Horn Wont Blow, and Cruise Control Wont Work 2000 Chrysler Grand

Check all your fuses first, if OK, ck for power at the horn. Are your cruise controls on the steering wheel or on a stalk on the side? If on the wheel, I would say it might be a clockspring issue. In this case, the cruise and horn both use the same clockspring to get power. The clockspring allows power to go to the buttons on the wheel without breaking wires from the wheel moving during driving, Chryslers are known for breaking clocksprings. The clocksping is located inside the steering column and is not an easy fix. You have to pull the steering wheel. Do you hear a click, feel a tick, or feel anything unusual in the steering wheel just prior to these issues. Sometimes you can feel the clockspring break, the wheel will "catch" for a second before the plastic breaks inside of it.

Open up the hood of the car and look at the horn cord (it should start in near where the steering wheel is) see where is ends you just fill up the container with water
