1998 Lexus gs speedometer not working?

If the speedometer in your 1998 Lexus GS is not working, it could be due to a faulty vehicle speed sensor (VSS), a broken speedometer cable, or an electrical issue such as a blown fuse. First, check the vehicle speed sensor and its connections, as well as the instrument cluster for any visible damage. If these components seem fine, it may be worth consulting a professional mechanic to diagnose and resolve the problem, as it could involve more complex electrical issues.
