Ever have a windshield wiper arm, or rear window wiper arm, break off? We did. This video shows how to replace the rear window wiper arm and blade on a 2011 Honda Odyssey van, but it's essentially the same process for most newer vehicles with this style arm.

Maybe your window wiper arm didn't break off but it's just not putting enough pressure on the window to clear away the water. That could mean that the wiper arm spring is worn or broken. In that case, you'll want to follow these same instructions to replace the wiper arm.

The steps are simple:
1. If the wiper arm is still on the vehicle, remove the plastic cap at the base of the arm. You should be able to remove this by simply prying up on it with your fingers.
2. Remove the nut that is holding the arm in place.
3. Use a wiper arm/battery terminal puller tool to remove the arm.
4. Press the new arm on in the same location as the original.
5. Reinstall the nut and tighten it.
6. Clip the plastic cap back on.
