I have a 2002 Caravan and have been having wiper issues. Like some of the other posts I have had wipers with a mind of their own a few times, but my problem is they seem to go out of timing. The wipers will work properly then sudenlythey will contact each other, bending the ends of the wiper blades. This has happened three or four times in the past six months. Any help would be greatly appreciated.

 

Sounds like the same problem I was having... try tightening down on the 15mm nut that holds the wiper arms on the posts, that should fix your problem.

 

I'll try that. Thanks for the help.
