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

  A: Start front wiper motor servicing by removing the front wiper arm head cap with a small screwdriver after taping its tip. Then unfasten the 2 front wiper arm covers using the screwdriver. First operate the wiper to automatically position the windshield wiper motor at its stop point to enable removal of the front wiper arm RH nut followed by the LH front wiper arm nut. The cowl top ventilator louver sub-assembly must be extracted by taking apart its 6 claws. You need to unplug the connector before removing the 4 bolts that will detach the windshield wiper motor and link assembly. The windshield wiper motor assembly should be separated from the windshield wiper link assembly through a screwdriver disconnection of rod meshing at the crank arm pivot followed by removal of its 3 bolts after hand-turning the crank arm. Installation requires first applying MP grease to the crank arm pivot of the windshield wiper motor assembly followed by bolt attachment to the windshield wiper link assembly where they must achieve 7.5 N.m (76 kgf.cm, 66 in.lbf). The wiper motor and link assembly needs installation with 4 bolts where a torque setting of 5.5 N.m (56 kgf.cm, 49 in.lbf) should be used before connector reconnection. The procedure for front wiper arm LH installation requires first operating the wiper until the motor stops automatically then using a round file to remove its serration section followed by wire brush cleaning of the wiper pivot serration before installing the front wiper arm with a nut torque set at 20 N.m while manually maintaining the arm hinge position. The front wiper arm RH must be installed using a nut tightened to 20 N.m (205 kgf.cm, 15ft.lbf). While performing this step maintain hand pressure on the arm hinge. End the process by running water or washer fluid while operating the wiper to verify the wiping performance and avoid damage from wiper contact with the vehicle body.
