• Q: How to replace the windshield wiper motor assembly on 2003 Toyota 4Runner?

  A: The windshield wiper motor assembly replacement process starts with the removal of front wiper arm head caps through small screwdriver disassembly of 2 caps while protecting the screwdriver tip with tape. The wiper operation allows the windshield wiper motor assembly to reach its automatic stop point then permits the removal of the right-hand side wiper arm nut before the left-hand side wiper arm process. Orderly remove front fender-to-cowl side seals on the left and right sides by unclipping the attachments while releasing the claws. Detach the cowl top ventilator louver sub-assembly by first removing two clips along with using a clip remover to unfasten six clips before unclipping nine claws. Remove the windshield wiper motor and the link assembly by disconnecting its connector and removing two bolts while sliding the wiper links to the passenger side past a rubber pin. To remove the windshield wiper motor assembly first disengage the meshing between two rods at the clank arm pivot with a screwdriver and then remove two bolts from the assembly. During installation of the new windshield wiper motor assembly with 2 bolts use MP grease at the clank arm pivot and tighten bolts to 7.5 N.m (76 kgf.cm, 66 in.lbf). Hook up the windshield wiper link assembly by joining the rubber pin correctly and fasten it with 2 bolts secured at 7 N.m (71 kgf.cm, 62 in.lbf). Finally, reconnect the connector. Install the left front wiper arm by first stopping the wiper at the automatic stop position before scraping its serration part with a round file and cleaning the wiper pivot serration with a wire brush. Then attach the arm with a nut while holding the hinge and fasten it to 25 N.m (255 kgf.cm, 18.4 ft.lbf). The wiping functionality and the rear wiper clearance should be checked by running water or washer fluid across the window after both right front wiper arm installations are torqued to 25 N.m (255 kgf.cm, 18.4 ft.lbf).
