Question about 2005 Chevrolet Trailblazer Ext
The gauge moves sometimes, but now it won't move at all, even when the tank is full. not sure if there is a separate fuse for the gauge.
No, unfortunately it does not have a separate fuse.
The fuel gauge receives a fuel level serial data message from the ECM/PCM and displays it. You may want to check with your local Chevy dealer and see if there is any instrument panel cluster software updates available to correct the problem. If not, chances are the gauge is defective.
Good luck and let me know.
