lube it up and move the arm back and forth till is free.
Back and forth as in close to the glass and away from the glass.�
NOT in the direction it moves as if to clean the glass.�
Its just crud built up where its supposed to pivot so the spring there can put tension on the arm to press against the glass.

Subject: Rear wiper no wipe
 

Hi everyone.
1985 Westfalia that spends winters inside and summers outside.
My rear wiper doesn't have any tension on the window.� Wiper motor works fine (maybe a little slow to warm up then works ok).� Any ideas how to get it working properly?
Is it just a matter of removing, cleaning/lubing, replacing?
ThanksJeff
