I have a 1992 LS 400 and am generally very satisfied with the car. However I have an irritating problem whivh I cannot seem to solve. Soon after I bought the car the LED display on the centre consol which indicates the time and temperature began to fade. It got fainter and fainter until it completely disappeared. Now it's only visible about one day a year when it is unbearably hot and the inside of the car is like an oven!. Obviously I could replace it, but the time and expense involved would be considerable. Is there another way?
