• Q: How to replace the windshield wiper motor assembly on 2005 Toyota Sienna?

  A: Start the windshield wiper motor assembly replacement by taking off the front wiper arm head cap using a small screwdriver after taping its tip. First stop the windshield wiper motor assembly at its automatic position through wiper operation then unfasten the front wiper arm RH nut followed by its removal and finally unfasten the front wiper arm LH nut. The cowl top ventilator louver sub-assembly can be removed by detaching its 6 claws. Separate the connector followed by removing the 4 wiper motor & link assembly retaining bolts. The first step for the windshield wiper motor assembly is to free the rod from the crank arm pivot with a screwdriver before removing its 3 bolts which allows detachment from the link assembly. Pre-handling the crank arm aids this procedure. The installation of the new windshield wiper motor assembly requires application of MP grease to the crank arm pivot followed by securing it with three bolts at 7.5 Nm (76 kgf.cm, 66 in.lbf) torque. The wiper motor & link assembly installation requires 4 bolts which should be torqued to 5.5 Nm (56 kgf.cm, 49 in.lbf) and then connect the connector. Install theanine front wiper arm LH only when the automatic stop position reaches the wiper motor assembly. Cut off the wiper arm serration piece with a round file then wipe the wiper pivot serration with a wire brush and bolt the arm into place with the nut tightened to 20 Nm (204 kgf.cm, 14.8 ft.lbf) while maintaining pressure on the arm hinge. Holding down the arm hinge install the front wiper arm RH with a nut torqued to 20 Nm (205 kgf.cm, 15 ft.lbf) after you perform scraping and cleaning. Use water or washer fluid running across the window as you activate the wiper to verify the wiping performance before inspecting for wiper contact with the car body.
