I have a 93 LS400 that had one bad needle, and a non-functioning gas guage. I found a guy (an electrical engineer) in MN who has a lot of experience with repairing ALL Lexus instrument problems. I sent him mine, after speaking with him on the phone. It was repaired within 24 hours, 2 year warrantee, and works great. All much less expensive than the dealer. Email me if you like, I'll send you his name, Phone# and email address. Also, the removal of the instrument cluster is actually fairly easy. I can give you a few hints on that too. Email me at "jswett@optonline.net"
