Steering Wheel Radio Controls

(2003 Buick Regal)
in North Highlands, CA on August 25, 2009
While driving with the radio on, turning the wheel sometimes will jump the volume up. Controls work intermitantly. Any answers would be appreciated.
Thank you, David

I would suspect you have a problem with the steering wheel air bag "clock spring". The clock spring is a coil of wire which will wind and unwind as you turn the steering wheel. The circuits for the steering wheel radio control also pass through this coil assembly. Broken wires in this coil assembly are not uncommon and if a wire is grounding intermittently that could cause the volume to change by itself. Confirming this fault with a volt/ohm meter is possible by may be a bit complicated.
