1998 pontiac grand prix will not spray windshield washer fluid

This is most likely the washer pump. I just replaced mine today. It is located on the right side, in front of the wheel, behind the wheel well cover. you will need a phillips screwdriver to remove the srews that hold the wheel well in place. Just remove the ones to the front of the tire and under the bumper skirt. This will give you just enough room to access the pump. The pump is attached to the fuild tank. Disconnect the electrical from the pump. Drain any fluid into anothe jug - as when you remove the pump fluid will leak out. You may need a small screwdiver to gently pry between the pump and the tank to release the upper hold on the pump, then rotate and pull the pump out of the tank. Its held in by a rubber type grommet. Reverse the steps to reinstall. Hope this helps. Good Luck!
