Tachometer not working

Ok folks I need some ideas. I've searched and haven't found an answer.

So in the past 3-4 months my rpm gauge stopped working 2 times. After I turn the car off and let it sit it will work. Everything else runs and works perfect. Please help

 

Hmm, I have to research this one....

 

Everything I reading is leading up to a bad Tach in the instrument cluster.....does it randomly work?

 

@RonT4R it randomly doesn't work is more like it lol I bought the T4R this past Jan and its only not worked maybe 3 times. And it only lasts till I turn it off and let it sit for a little. Then it works fine again.

 

I mounted by GPS over the tach, my needle fell off. I've never understood the use of a tach on an automatic any way.

 

LoL that is true! Guess I'm more worried it could end up being something that effects how it runs. Guess I'll worry about that if or when it happens

 

quit banging on the rev limiter lol how the hell does your tach needle come off?
