• Q: How to service the front wiper motor on 2006 Toyota Highlander?

  A: The service process for front wiper motors starts with uncovering both windshield wiper arm covers and removing the front wiper arm and blade assembly LH by detaching its nut. Continue with removal of front wiper arm and blade assembly RH using the same process. The service process begins by removing the cowl top ventilator louver sub-assembly through disengaging the 6 claws, taking out the 2 clips before disconnecting the connector and removing the 2 bolts to extract the windshield wiper motor and link assembly by disengaging the pin. A screwdriver wrapped in protective tape must first disengage the upper and lower rods of the windshield wiper link assembly from the crank arm pivot before removing the 2 torx socket wrench (T30) bolts. The installation process requires screwing the front wiper motor into place using the 2 bolts accessed with a "torx" socket wrench (T30). Torque these bolts to 5.4 N.m (55 kgf.cm, 48 in.lbf). After cleaning the crank arm pivot, attach the 2 rods to it. Install and torque the windshield wiper motor along with its link assembly using the 2 bolts and pin to 7.0 N.m (71 kgf.cm, 62 in.lbf) while also reconnecting the connector. First reinstall the cowl top ventilator louver sub-assembly and run the wiper until the front wiper motor stops automatically for cleaning purposes. After cleaning both wiper arm components and their serrations, install the right-hand front wiper arm and blade assembly with the nut while applying 24 N.m (245 kgf.cm, 18 ft.lbf) torque and securing the arm hinge during fastening. The service technician must repeat the cleaning operations and installation for the front wiper arm and blade assembly LH. This must be followed by mounting the 2 windshield wiper arm covers and performing a wiper test while applying water and washer fluid to the windshield for proper wiper evaluation.
