I have an 02' UL LS430 and the light on the seat heater/ac switch on the dash no longer lights up at night. This is the seat climate control switch on the dash just to the right of the shifter. Has this happened to anyone else? Is it a simple matter of a bulb replacement or does the whole switch have to be replaced? Any advice would be greatly appreciated as I am taking it to JM Lexus on Monday to get a new steering wheel and I wanted to get this fixed also.

Thanks,
Ed
