The only thing wrong with my 9-3 is that the cruise control doesn't work. I can get the "cruise" light to come on but nothing else. Someone says there is information available to correct it, but I have been unable to find it.

Can someone suggest a diagnosis method?

Do you have any other warning lights on?

If not, the first thing to check are the brake and clutch switches. If the ECU sees either pedal as "pressed", it will belay the cruise request.

I do have an airbag error and I know why. I made sure the clutch and brake pedals were returning but I haven't found the switches yet. I will search this week end.
Thanks for the reply
