TOYOTA INSTRUMENT CLUSTER GAUGES ENGINE TEMPERATURE

I Purchased My Celica About A Month Ago And Already Had To Put A Different Engine In It Because It Threw A Rod Through The Engine Block....

My Temperature Gauge And Compass Is Not Working. Is There A Fuse I Need To Replace Or Do I Need To Bring It In For Service?

Car Warmed Up, Runs Okay, Fluid Level In Overflow Container Okay, But Engine Temperature Just Above Bottom.
