Boy that was unnecessarily difficult to work out!!

1) Pull it out - push the new one in!!

It's that easy.........(New wiper blade $12 from my Calgary Hyundai Dealer.)

2) If you have to remove the arm pull off the plastic cover from over the spindle - think of it as "U" shaped and gently pull the legs of the "U" apart. I will fly off and probably onto the floor!

3) If you haven't looked under there for a while you might want to remove that cover (and maybe the arm) and put a little grease on it. Strange how so many part were made to resist corrosion but then I keep finding parts that aren't!
