Not sure the source is the same problem, but I recently had a problem involving lights and camera switches. We were headed north on I-85 and I began to notice when I turned the switch to signal lane change, the cameras would not change to side view. The signals still worked, but the normal 'click' associated with the light flashing did not happen. Then the window just above the steering column that contains all the checklist info, odometer etc was black. The ABS light was on and the bright lights indicator light was on, even with no headlights on, and the engine off.
Since we were about 12 miles from Gaffney, I called Pat at the shop and she was able to get us worked in as an emergency. The guys at the shop worked quickly and got us back on the road within a few hours and we were able to make it to Virginia in time for the meeting. As it turns out, there is some sort of control module with the Smart Wheel that had gone bad. I have heard stories from other folks about the Smart Wheel not being quite as smart as it should be. Pat and the shop crew are absolutely the best. The techs turned the wheel and the horn blew - knowing this not right

they checked the wiring in the steering column and found an abraided portion of wire shorting and making the horn blow. Fixed this as well. Good folks at Gaffney.
