check the fuse.
The Chrysler Sebring cruise control switch is located beneath the dashboard, on the drivers side. The cruise control switch should be labeled as such.
I had the same problem. It is the clock spring in the steering column and I took it to the dealer and they fixed without charge it under a recall. Check out Chrysler's web page for recalls.
2004 sebring convertable cruise control not working - what to do?
The engine computer controls the cruise.
as it says here http://en.allexperts.com/q/Chrysler-Repair-807/cruise-control-dodge-neon.htm you could check the vacuum cable. I have the same problem on the same car.
The most likely common cause is a failed clockspring in the steering column.
The cruise control is fed by the pcm. If the car starts there isn't a blown fuse.
Answering your question concerning the horn relay . I have a voyager 98 ,my horn and cruise control was not working so the problem was from a piece name clock spring located under the horn and cruise switches in the (direction) . So when i changed this clock spring both problems where solved . The clock spring is under warranty from Chrysler/Dodge due to a factory recall. Check with your local dealer to see if your model/year is covered.
There isn't a separate fuse for the cruise. The switch has probably failed.
the cruise control is broken....
cruise control does not work when headlights are on
The cruise control is powered by the engine computer. If the engine runs, the fuses are ok.
