How to FIX Slow Moving or Seized Windshield Wipers

Watch the video

Remove the windshield wipers by removing one bolt at the bottom and pull it right off the threads

Take out the bolts holding in the whole mechanism and you should be able to move it around a little bit.

Use a pickling fork to pry off the two arms being careful not to shatter the windshield.

It takes a lot of patience and wiggling to take out the mechanism but if you get in the right position it will come out. Then you can take out the power plug.

To take off the arm put oil on it and wiggle it off.

First, take a file to the post to take off the big crud and grit. Then take sandpaper and sand the post and the inside of the arm. If you put the arm back on it should be able to move like is supposed to.

If you break the arms on the mechanism (like we did) here is how to fix it. Mark where to drill the holes with a nail and drill out holes on both sides. Grind the head of a bolt off so it is a consistent diameter. Then tap one of the holes and thread in the bolt you just ground. Put J-B Weld on the side you ground and slide the two together. You can wrap tape around the joint to keep to glue contained.

With pliers squeeze the arms back together and wiggle the whole mechanism back into place and bolt it down.

Now just button every thing back together and it should move just like how it used to!!
