My 2004 Lexus SC430 has a problem - no instrument cluster back light, fuel gauge and temp gauge don’t work and the VSC & VSC off light stay on. Everything else works. All fuses are working. Lexus and others can’t pinpoint the fault using diagnostics but suspect it’s the combination meter or control unit. They can’t source them as they have been discontinued but think that they can be repaired. Does anyone know of someone who can help diagnose, replace or repair. Thanks Mike
