My 06 RX 400h steering wheel control buttons stopped functioning today. They do not even light up. I do not see any fuse listed on the box for it. Does anybody know of a fuse to check so do not waste my time pulling fuses looking for the right one; or if it even has a fuse. Thanks

 

I pulled every fuse in the car and they are all good. Tried disconnecting the battery, no good. Unless anyone has advice, my baby is going to the doctor's office next Monday

 

I unplugged the radio, looking to see if the wires that control the steering wheel buttons had any issues and when I plugged everything back in - walla the buttons now work.?.
Maybe it will help someone else in the future.
