• Q: How to service and repair the wiper linkage on 2006 Toyota Prius?

  A: The service and repair process for a front wiper motor and linkage begins with unmounting the front wiper arm head cap and continuing with removal of the front wiper arm LH after loosening two nuts followed by front wiper arm RH unmounting after nut removal. The service requires detachment of 8 clips and then execution of the hood to cowl top seal removal followed by using the 8 claws and clip to remove the cowl top ventilator louver LH and completing the same procedure for the cowl top ventilator louver RH. Use a screwdriver to disconnect the connector before uninstalling the five bolts which will extract the windshield wiper motor with its link assembly. Deliver the flat-head screwdriver between the windshield wiper link arm and crank arm pivot of the windshield wiper motor while using tape on the screwdriver tip first, then remove the nut and washer followed by the crank arm and document the mark positions for reinstallation before taking out the windshield wiper motor using the 3 bolts. Install the windshield wiper motor to the windshield wiper link by inserting the 3 bolts with 5.4 N.m (55 kgf.cm, 48 in.lbf) torque before installing the crank arm and its washer and nut with correct matchmark alignment at 17 N.m (175 kgf.cm, 13 ft.lbf) torque and applying MP grease to the crank arm pivot prior to windshield wiper link arm installation. Put the 5 bolts on the windshield wiper motor and link before torquing them up to 5.5 N.m (56 kgf.cm, 49 in.lbf) then reattach the connector. Insert the front wiper arm LH after cleaning both components and installing its nut with blade alignment followed by nut torque to 21 N.m (214 kgf.cm, 15 ft.lbf) under arm hinge constraint. Utilize water and washer fluid during front wiper operation to check the devices' proper function and clearance after performing the cleaning and front wiper arm and blade assembly RH installation process with two nuts. The cowl top ventilator louver RH should be installed by securing 8 claws and a clip while the same installation process must be repeated for the cowl top ventilator louver LH. Reinstall the hood to cowl top seal by using all 8 clips and connect the negative battery cable before performing initialization. System initialization needs to be done after negative terminal disconnection and reconnection.
