Yes. Look in the Fuse Panel inside the Truck. Use a Good Maglight or LED Flashlight and Hold it Behind the Fuses to see the Blown Ones. It is usually in an AUX Outlet. Also check thr Fuse Relay Box under the Hood for a Blown Fuse using the Same Method. See if there is a Relay for this also. If so, Replace it. Let me know if you need any more Help!

there is one fuse for all the dash gauges, so chances are you have a wiring problem to the gauge sender on the engine or the gauge is defective, which is rare.
