93ls400walt Posted November 23, 2008 Share Posted November 23, 2008 common issue on these cars. It may work intermittently. Some people say a hard tap on the dash above the tach helps now and then. options are to buy new/used circuit board for the inst cluster, maybe repair. Do a forum search for further info.
