One interesting side note. One of the lights behind the heater controls went out on me for about a week about a month ago. It seemed to fix itself. It came back on again and has been working since. Maybe the light behind the tach will come back on also?
This happened to me also and it just started working again.....but I don't think your going to have the same luck with the tach light. And it just sounds like a pain in the ass to get up in there
