Hello!! Z fans.
When I warm up my car in the morning the temp. gauge will show its warmed up. As I drive the car the gauge shows the temp. at cold, and later it shows at warm. I does this every time I drive the car. Please help my 280z
> Sounds like it's just a bad connection or grounded wire. the power off position is to cold, so whenever the bad connection or wire
grounds itself the gauge simply goes to the off
position. Make sure the fuse is new and the fuse box dry (no rain leaks); then it looks like a Saturday moring with a wire diagram to trace the problem.
