Hi all,
I also have the same problem. To get the tachs working, I would have to bang on top of the dashboard. I called the lexus dealer and they said it was the instrument cluster that is going bad. They quoted me $1200 for the part and $250 for labor.
Curt,
If you could provide us a step by step procedure on how to fix this problem. I would greatly appreciate it.
Regards,
Jim
