04 WIPER PROBLEM

2004 Toyota Sienna • 4WD Automatic • 90 miles

I have a 2004 Toyota Sienna, When the wipers are on they reach what would be the park position, stop for less than second, extend past the park position for an inch or two. Then contine to wipe the windshield. This happens on every wiper stroke. Is there an adjustment.

When wiper arms are parked, are they in the correct position or are they too low?

Was anything done prior to this occurring?

The wipers are a little high when in the park position. To add a little more detail, on every wiper both wipers go down for an inch or two and the compelte the full stroke.

There was no repair work done, however there was a bad ice storm. And the wipers started to act funny after the ice storm.

Operate the wiper while running the water or the washer fluid over the window, and check the wiping condition and that the front wiper does not hit against the vehicle body. Readjust if necessary.
