The ground wire on a typical Chevrolet truck should be located at the rear of the vehicle. The wire should be white in color, and should be attached to the frame by a screw. You may need to remove the tail light housing and trace the wire from there as the location varies on different models and years.

The ground wire going from the cab of the truck to frame and/or the ground wire going from the back of the motor to cab ground. The reason is that the ground wires lay across the exhaust manifold and get burnt off after a years of use.

The turn signals are not fused front and/or rear. If the rear are not working you need to check for power and grounds for the lights.

Check the ground wire for the rear lights in back underneath where it attaches to the frame/body/bed. It may be broken, corroded or loose.
