Is there a way to conceal the windshield washer tubes?
Conceal the washer tubes that GM stuck on the outside of the blade arms. Just drill a small hole for the tube to fit through just below where the blade attaches and on the back side of the arm. Then thread the tube through the bottom of the arm (by the spring) and up the hollow metal arm and out the hole that you drilled. I did this several years ago and it looks and works great.
