My controls on my steering column all work except for my music buttons. I have a navigation system and music center and it will not work either. The lights on the buttons are all lit up and there is some backlight on the lcd screen but its still black. My passenger air bag off light is not working all the time. This just started happening yesterday. My battery in my truck has been going bad and have had to jump it a few times with a battery charger. Jumped it yesterday morning and saw the lcd screen for the music would not come on and the only thing i could do was adjust the volume of the music which was still playing. Put a brand new battery in today and now that does not even work. I can get the air bag light to work some but not how it should. Anyone have any ideas?
