Dan, my name is David W Rynders and I have had various kinds of trouble with the instrument panel in my 1993 LS400 over the years (I still have it and love it). First DO NOT take this problem to any dealer or other garage, even a Lexus specialty garage. Enormous waste of $$$.
Other people may have their favorites, but the series of problems I experienced did allow me to weed out some of the bad "instrument panel" repair shops around the country. My experience: By far, the best, cheapest and most reliable outfit is BBA Remanufacturing Inc., 300 Miles Standish Blvd., Taunton, MA, Ph: 1-866-573-2740. You can pull out the instrument panel yourself with remarkably ease (granted, doing it five times increased my skill.) BBA will send, maybe email, you instructions if you need them. Basicall, you will remove a couple of small paned sections, unscrew 3 or 4 screws along the top of the panel itself, slide out the front and put it aside (in a protective box or something), then unplug a couple of small connectors - these are fussy but each has a place where a small tool will release the locking clip and then you can gently slide them apart with your fingers or wiggle something between them to pry them apart. Next you will probably have to start sliding the panel out and wiggle your hand behind it to unplug several larger connector sectiions from rear of the panel itself - this will be challenging but if you can commandeer a small child to reach behind and aid him or her by unlocling the clip, usually in the centerof the connector, with a small pry tool, they will eventuall come free and then the panel can be wiggled out - it helps to have set your steering column to its lowest point - I started out removing the cover to the steering panel then discovered it wasn't necessary. Once the panel is in your lap, BBA will send you a UPS address label for you to paste on a box in which you have carefully, with lots of cushioning, packed the panel. UPS will pick up the next day and in about 10 days or 2 weeks, your panel will be returned to you for re-installation in roughly the reverse order of actions described above. They will charge between $200 and $300 depending on how many problems you have to fix. Shipping costs - both ways - may total $50, probably less. And they give you a guarantee!!! A real one! Mine had more problems about a year after the first fix (by BBA, I don't want to think about the three earlier, stupid, wasted efforts), & I called them and they sent me a shipping label, I shipped it to them and it was returned completely fixed in ten days WITHOUT ANY cost to me - not even for shipping. Please let me know if this works for you. David
