Nole65SG Posted October 3, 2006 Share Posted October 3, 2006 I replaced the gauge cluster on a 92 Lexus SC300. The needle lights on the old cluster were not working and the speedometer and tach only worked intermittently. I found a used cluster and had it installed. The needle lights now all work fine and the speedometer and tachometer both appeared to function properly. However, by the end of the day the speedometer and tach were back to zero and not working again---or working only intermittently as in the past. Needle lights, however, are fine. Any ideas what the problem is with the speedo and tach and how to fix? Thanks. Quote Link to comment Share on other sites More sharing options...
