My cruise control will arm but I cannot get it to set the speed. The green "cruise" indicator light comes on but when I push the set button on the stalk it doesn't do anything. the other day my radio would not turn on at all, I just got the red blinking LED like the doors were locked. So I shut off the car locked the doors, unlocked and it still would not come on. the next day it still would not come on so I disconnected the battery for about a half hour. When I hooked it back up the radio came on and the cruise control worked again. Later that day the cruise control went out again. Has anyone had this happen to them?
