rear wiper getting stuck

[Electrifyliak]

A few months ago, my rear wiper started getting stuck in the space between the door and the window that flips open. If I get out and bump it (or blast my subwoofer real loud) it will get on the window and start working. Has this happened to anyone else? Any ideas on how to fix it? The only idea I had was to maybe put some silicone or something in that space but it might just stick on that too. Let me know what you think. Thanks.

my wiper arm would get stuck all the time, i took it apart and sprayed some fluid film in between the nut that holds the arm on and the mount on the outside back of the rear hatch. It loosens up the pieces that get the most friction together which inturn gives the arm a more free range of operation. It gets sticky from all the salt around here in the winter time. Just keep spraying and moving the arm repeatedly to get the lube in there and it should work like a charm again
