donbryce Posted July 23, 2010 Share Posted July 23, 2010 Hey my rpm gauge is not working on my car. anybody know how to fix it http://manualspace.com/toyota-lexus-es-300-1993-factory-service-manual.htm Find the guage cluster removal and disassembly instructions. There are several screws that double as mounting screws and electrical contacts. My tach was missing a screw from a PO's botched attempt to upgrade the backlight bulbs. Yours may have a loose or missing one. If not this, then look for a wiring issue. Quote Link to comment Share on other sites More sharing options...
