Lexus LS400 '93 and '94 have a problem with the instrument cluster lights (dash lights). Many many people have this problem. The dash lights won't come on for a while, then they will flicker and finally come on. This is more evident in cold weather. This problem gets worse over a period of weeks or months until they will refuse to come on at all. When the light are off, the fuel gauge points to empty as well.
The problem, I found, is in the power supply circuit boards. They are located behind the instrument cluster. I have compiled some detailed instructions on how to remove those boards. If you want a copy of those instructions, just Email (PM) me. I'll Email them to you, no charge. I would attach them here, but they are larger than the 102.4KB limit on this board.
My car did that. '93 LS400. The Lexus dealer wanted $1400 to repair it. I repaired mine myself, I'm an electronics engineer and I can help you repair yours too! Email me or PM me
