on some cars the cruise control cuts out on its own in Case you have fallen a sleep
Check your fuses first; you may have a bad fuse.
Blown fuse would be where to look first.
Mine didn't quit, why ask me? :-) Check the fuses first.
The most probable cause for your malfunctioning cruise control is a blown fuse. The fuse might have blown while you were changing your switch. The cruise control fuse can be found in the fuse box.
It is possible that both of the fuses are bad for the low beam headlights and the cruise control. A loose ground wire could cause the fuses to blow.
Most likely loss of refrigerant.
It depends on the year. Ford had a recall on their cruise controls. They had a faulty switch on the brake master cylinder. yes but it could get hot and get a short in it

1. You have a problem with the cruise control. or 2. If your check engine light is also on, get the code read, cancel the light and the cruise indicator light will probably quit flashing and the cruise will start working again.
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.
