With the window rolled all the way down, the damn crank handle knob sits EXACTLY where I rest my knee. Totally irritating. I want to rotate the crank 180 degrees but I can't figure out how to remove the crank handle from the stem. I know theres some sort of retaining clip or some such nonsense but I can't see it and I don't know how to remove it. I probably need some $100 Escort-specific window crank tool.
