Wiper Transmission, Front

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.
