I have a 2000 Intrepid. I start the car and turn on the cruise control. The light comes on for 10 seconds then turns off. I have to turn the car off and on to get the light to come on again. But it still goes out after exactly 10 seconds. If I push the brake pedal before the light goes out then it stays on until I release the brake. I am never able to set the speed even when the light is on. I assume some check is going on during those 10 seconds and something is failing and that's why the light goes off. I check the computer and there are no error codes. Does anyone know what part of the cruise control system is failing and how do I test for this failure?
Thanks for your help.
