You will need to remove the little wiper arm first by taking off the retainer nut. Then disconnect the tubing from the jet on the wiper. Then you have to remove the right directional lamp housing. Can be done from the inside of the engine compartment by depressing the clip that holds it in place. Then you will expose the outer retainer screw for the trim panel below the headlight. The inner is already out in the breeze. Take off the screws and you will be able to get at all the tubing for that wiper. Follow it back to the split. You should be able to find your leak..

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
