2005 Cruise Control
 

I have a 2005 Malibu with 25,000 miles. Got in the car last night and tried to turn the cruise on and it wouldn't work. Yellow light on the left hand switch comes on but the green light on instrument panel doesn't come on and obviously the cruise won't engage. Absolutely no problems at all the last time I used it and have never had any problems turning it on before.Haven't noticed anything else in the car [radio, lights, turn signals, &c.] not working properly.Help! Anybody know what's wrong?
