CDULUK,
Thanks for the reply. No I am not sure it is burned out. It just doesn't light when the switch is pushed a number of times. But the actual air valve changes, so the switch appears to be working. I was thinking that maybe the movable push button just pops off, and the LED then might be accessible. I'm not sure I want to pull the center dash apart just to get to the light. Maybe someone else has an idea how to check what is wrong if the LED doesn't light.
