Question: Gas gauge not working

When the tank is full the needle will set on the
full mark. When the fuel level gets down to a
little over half full, the needle will start bobing down and back up and finally will rest on empty
and stays there until more fuel is added. Also
the windshield washer light remains on all the
time since the gas gauge problem started.
Is this a sending unit problem or the gauge?

Gas gauge: likely the sending unit in the tank is going bad and will need to be replaced (if you want an accurate fuel tank reading). You'll have to take out the fuel tank to access it (or unbolt the truck bed and lift it up).

It doesn't sound like the same problem as the washer tank, but you can ground the wire to the sending unit to see if the gauge pegs. If so, the problem is not the gauge.

It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
