I own a 2001 Wrangler Sport with a hard top. When I bought my Jeep, every time I hit the rear windshield wiper fluid, it didn't seem to work. I then found out the hose was leaking all over my carpet. My friends Wrangler has a little plug/elbow piece that is connected to the hose to the outside of the hard top. I have asked people and I cannot figure out what this part is to other a new one. I have tried rigging it to work and nothing. Can anyone help?
