What could be wrong when my cruise controle and radio buttens on the stearing wheel do not work .It did work but after a while it stop working . volvo v70 2003
There is what is called a clock switch located under the steering wheel that must have went kaput. it is what transfers the signal to the steering column.

How about the turn signals, are they working? If not, then pull the fuse for the Steering Wheel Module (SWM) to reset the module. There is software upgrade from Volvo to prevent this in the future!

Check the brake switch below the brake pedal. It may think the brake is being pressed if that switch is not working properly. Also check for vacuum hose leak or damage in the same area.

could be a bad clocksping the airbag is on it to but one of the thin film "wires" that are glued to it may have cracked.all the switches are on one "wire" the resistance of each switch is how the body control computer knows what button is pushed. i broke one of those clocksprings accidently when i worked at volvo so thats how i know those things are/were 1400.00$ i would take it to the dealer to have them diagnose and repair. the clock spring breaks real easy when you take off the steering wheel.

it appears there is a computer program upgrade for a few cruise control problems on your car. can only be done at a volvo dealership though. call them and see if any would applie to your cars vin# they dont give out any info online exept for that there are problems with the cruise control and the "fly by wire" throttle control. they may be more exspensive at the dealer but they have the proper tools and information needed to fix the car. in the long run it will be alot cheaper than throwing parts at it.as a side note that car is what is called a networked car.meaning even seemingly simple parts like a seat or window switch are actually computers. that is why i asked about any new electric parts., if a used part were to be installed it would be very likely the programing in it would disagree with your car causing a software coruption problem ranging from wierd minor stuff to failure to run at all. a new part would be unprogrammed and cause the same problems.

Sound to me like you have blown a fuse. Anything else not working?
