  Q: How to service and repair the Wiper Linkage on Scion xA?

  A:

  The wiper motor linkage repair and servicing process starts by disconnecting the negative battery cable terminal for at least 90 seconds to avoid activating Air Bags and seat belt pretensioners. Function the wiper to reach the automatic stop position and then detach the front wiper arm head cap followed by both left and right wiper arm and blade assemblies. The removal of the hood to cowl top seal requires a clip remover to detach its 8 clips and associated seal. Both left and right side cowl top ventilator louvers require unfastening their clips and bolts and detaching their five claws. Detach the windshield wiper motor while disconnecting its connector then removing two bolts followed by sliding the wiper link toward the passenger side to free the rubber pin. Start by detaching the windshield wiper motor assembly with a screwdriver which removes the meshing of the 2 rods at the crank arm pivot followed by "torx" bolt removal. Install the windshield wiper motor assembly onto the wiper link by tightening two "torx" screws to 7.5 N.m (76 kgf.cm, 66 in.lbf) neither losing nor gaining a pre-established tolerance. After application of grease to the crank arm pivot, insert both rods. Installing the windshield wiper motor and its link component requires applying 5.4 N.m of torque (55 kgf.cm, 47 in.lbf) to 2 bolts. Finally, resume the connector. Both sides of the cowl top ventilator louvers need five claws to attach for bolt and clip installation. After fitting the 8 clips to attach the hood to cowl top seal you must install the front wiper assemblies on both sides while scratching off the wiper arm serrations and wiping clean the wiper pivot prior to torquing the retaining nut to 26 N.m (265 kgf.cm, 19 ft.lbf). After reconnecting the battery negative cable you must perform initialization because selected systems need this process.

  Q: How to service and repair the wiper linkage on Scion xB?

  A:

  A proper wiper motor and linkage service starts with disconnecting the cable from the negative battery terminal and allowing at least 90 seconds of sit time to deactivate the seat belt pretensioner and Air Bag. First separate the head cap of the front wiper arm then detach the wiper arm assembly with its blade on both right and left sides. The hood to cowl top seal requires a clip remover to separate its 5 fasteners and one retaining seal. Both sides require removing four clips and detaching five claws to remove the cowl top ventilator louver. Unplug the connector before taking out three bolts to remove the windshield wiper motor and link assembly. To remove the windshield wiper motor assembly utilize a screwdriver to disconnect the 2 rods at the crank arm pivot while taping the screwdriver tip to prevent damage and afterward decline the 3 bolts. To assemble the windshield wiper motor link use 3 bolts to connect wiper link to motor assembly at 5.4 Nm torque (55 kgf-cm / 47 in.-lbf) while applying grease to the crank arm pivot before reattaching 2 rods. The windshield wiper motor and link assembly requires installation using 3 bolts which should have their torque set at 5.4 Nm (55 kgf-cm, 47 in.-lbf) and the connector needs to be reconnected. Install the cowl top ventilator louvers by fastening the 5 claws to each side using four clips for both sides before applying the hood to cowl top seal which receives 5 clips. The left front wiper arm and blade assembly installation process requires operating the wiper to automatic stop position then scraping the arm serration part before cleaning the wiper pivot serration. The arm should be installed with a 20 Nm (205 kgf-cm, 15 ft.-lbf) nut torque while maintaining the installation position mark between 25 to 40 mm (0.98 to 1.57 in.). The installation position mark for the right side needs to lie between 29 to 44 mm (1.14 to 1.73 in.). Let the head cap of the wiper arm go on last before reconnecting the negativity charged battery cable.
