New to the forum and stressed out over my 2001 Vette. I brought it in 2001 as a retirement present to myself. It is my most treasured asset. My vehicle always seems to have these little electrical problems, I am not sure if it is because it sits for long periods. It currently has 18000 miles. The most recent problem is my “Heads –Up-Display.” I notice the tachometer no longer displays while the vehicle is running. The mph number displays fine. When I turn the vehicle off then back on the tachometer is visible in the Heads –Up-Display. What should I do?

When this happens, if the then you cycle through the various display options that the heads up display gives you on what and how it displays, is it only the tachometer that will not work and always the tachomter that won't work?
