[Already Gone]

I'm having issues with my temp gauge too. About a year and a half ago while driving it just went to cold and stayed there. During Highway driving it would move a little towards hot. Last summer in 80 degree weather with the A/C on and driving 75 MPH it went to half way.. The gauge is about 3 years old and the sender a year old with hardly any miles. I bought a new sender and installed it and no change and have good solid connection with original connector on the sender. All that is left is the gauge which I plan to change out in the sprig with an NOS one I bought. If anyone has any idea what my problem could be please post as I really don't want to pull my dash out. Oh yea my dash is a Speed Warning, Tach and Vacuum Gauge cluster redone by board member, PTs70CST, Paul Timmerman and only been in the truck for 3 summers.
