I've have my Z for a little over a year and just recently I noticed the digital gauge is now broken. It will say that its icy and 28 degrees when its 80 degrees and when I press the button to switch to mph or another reading it wont change. Sometimes it will change and I can get it to mph but it then has dash marks instead of showing me my speed, can anyone help me out?

 

Have you pulled the center console off and checked the wiring to the 3-gauge binnacle? Also, was the multi gauge working when you first purchased the car? On my '03 pre-order Z, this has been a very reliable piece of the electronics.

 

I haven't pulled it out and looked at it. It has worked fine until maybe a week ago.
