1998 jgc strange rear windshield wiper problem

Hello everyone,
I can't figure out why the rear wiper when turned on only appears to clean part of my window :screwy:
I think it might have been hit with an ice scraper or something.
when i watch the wiper it only wipes the first few inches of window then it lifts off of the glass all together. Any suggestions would be welcome.

check the spring in the wiper arm, maybe spray it down with some WD-40.

thanks i'll try that.

My '98 also experiences a similar problem. My wiper cleans enough so I can see, but it misses spots. I tried bending the arm a little but stopped, afraid I'll brake it!

I'll try spraying my spring too, never thought about that!
