one time the heads lights work the it don't changed bulb worked then didn't
This makes a lot of sense.If it is a ground problem it will be one of the three ground wires located on the hood hinge tower. Undo all 3 and use sand paper or a similar abrasive to clean both the wire end and the tower connection. I believe the left and right headlight fuses are in the under-hood fuse block. If you lose power to the light check to make sure there is power to the fuse for that side when the light isn't working.
