I have a 2000 Buick Regal. Sometimes the cruise control and Heat/AC blower fan quit then start working again later. At first I could turn off the car and restart it and the problem would go away. Now it might be 30 minutes of driving before they start working again. I have checked fuses but do not have a wiring diagram. Signals, lights, power windows and radio all work fine, just the cruise control and AC are affected. Any suggestions?

Sounds like it might be a bad ignition switch
Testimonial: "it was the ignition switch, way to go, thanks"

if you check in your handbook for the car under relays and fuses check both fuses or relay for burn marks you could have a problem with the fuse board
