I have a 94 LS400, first time owner, 118k miles, with the instrument light problems many of you have described. The guy who can fix it is Jim Walker! jimlwalker@sbcglobal.net Contact him and he will send you all the info on how to remove and ship the circuit boards to him. I had 90% of the symptoms you all have described and with Jim's repair my instrument panel works awesome. Down time approximately one week. I am in So Cal and on cool mornings ie: 60 degrees my lights would not work. Not a problem with this repair. You can also find him on ebay motors.
