1990LS400 Posted January 16, 2009 Share Posted January 16, 2009 The failure of a seat heater is often caused by a broken wire in the seat heater grid. A seat heater works much like an electric blanket. There is a long (11 page) diagnostic procedure in my repair manual for my 00 LS for the seat heaters -- too long to scan and post here and it might be a little different for your GS. The diagnostic procedure is mostly checking continuity and resistance. If you don't have access to a repair manual, the procedure can be downloaded from Lexus Techinfo.
