Yes they do........they just don't light up anymore. Drivers door window and lock buttons light up along with the heated seat button. The heated seat button lights up on the pass side......just the window and locks are out. The defrost is the only one of the 4 buttons in that panel that doesn't light up.
Don't know if this is the same, but I have an S truck and the lights in the window switch on the drivers door quit working, the dealer replaced the whole switch.
