• Q: How to service the rear wiper motor on 2007 Toyota Prius?

  A: A proper start to service the rear wiper motor requires users to disconnect the cable from the negative battery terminal for at least 90 seconds to stop Air Bag and seat belt pretensioner activation. Start by removing the rear wiper arm cover before moving on to separate the rear wiper arm assembly through the process of removing its nut and arm. The back door lower trim should be detached first then follow with the removal of the rear wiper motor assembly after disconnecting the connector and undoing its 3 bolts. The rear wiper motor assembly installation requires attaching it using 3 bolts with proper torque of 5.5 N.m (56 kgf.cm, 49 in.lbf). Finally connect the connector. Follow the installation of back door lower trim board assembly with rear wiper arm assembly locking the wiper motor at automatic stop point. The wiper arm serration needs treatment with a round file while the wiper pivot serration requires treatment with a wire brush before the arm and blade installation with a nut at 5.5 N.m (56 kgf.cm, 49 in.lbf). First secure the arm hinge with one hand before tightening the nut but make sure to align the blade against the defogger line before applying the cap. Reconnection of the cable to the negative battery terminal needs system initialization because a few systems require initiating procedures after cable connection and disconnection.
