speedo, temp, oil pressure gauges intermittent

[Hunterb]

My speedo, temp and oil pressure gauges have decided to only work some times. I find that when it is cold out they will not work and as the cab heat increases they will eventually start to work and then read correctly. I have searched this and have not found anything. I know there is a fix for the tach when it stops working and I'm wondering if there is a similar fix for this problem. If anyone has any ideas I would really appreciate hearing them.
Thanks in advance.

Sounds like a bad ground wire for the gauge panel. Try tracing that to the ground point, take off at both ends and clean, then tighten back down. Good luck
