I just bought a 1989 Reatta and am learning the ropes. I cannot find a way to illuminate the dash control buttons behind the wipers, defrost, cruise control or any of the buttons on the two columns of buttons on either side of the speedometer panel. I can't imagine there isn't some backlight to these buttons. Every time I want to use one of those buttons, I have to turn on the dome light to find the correct one. I have sort of memeorized the locations, but it seems to me that with all the other thought that went into the design of this car, that they would have left that out. any help would be appreciated.
