Similar issue

Thanks for the links.

I have a similar problem. After an ice storm, my wiper arms were
frozen in position. Once I broke the ice off, they found a resting
position at a 45 degree angle and twich every once and a while, even
though the setting is now at off. (And they do not move at all when I
do switch them on.)

I can physically move them back to the original resting position, but
it doesn't take long for them to find their way back up to the 45
spot.

My hope is it's just a matter of tightening something. But it might
be a link or motor issue. Any thoughts?

Thanks.
