In this video I go over how to take apart and REPAIR the rear wiper motor in my XC70.

There are a lot of videos out there on how to REPLACE the rear wiper motor. However that is not needed. In reality it is not broken. The output shaft has just rusted and seized in the housing.

You can save yourself a few hundred dollars by taking it apart, wire wheeling or sanding off the rust, adding some lube and re-assembling.

Lastly, my car is a 2004 XC70. I'm sure Volvo used this same wiper motor in other year and other model cars.
