Temperature gauge inside quit working. The heater works fine. Is there a fuse

Could be sensor, cluster or a computer issue

On 03-06 Silverados this is almost always a problem with the temperature gauge inside the gauge cluster. Each gauge has a motor that controls it's needle movement and when the motor goes out the gauge will either stick, jump around or die all together.
