• Q: How to replace the windshield wiper motor assembly on 2004 Toyota Matrix?

  A: Follow these steps to replace the windshield wiper motor assembly by starting with removal of the windshield wiper arm cover before stopping the wiper motor at its automatic stop position to detach the front wiper arm RH with its nut. Pass through to the front wiper arm LH by removing its securing nut. The hood to cowl top seal comes off by disengaging all 8 clips and afterward removing one clip and releasing the 5 claws needed to separate the cowl top ventilator louver RH. This procedure also needs to be done for the cowl top ventilator louver LH. The removal of the windshield wiper link assembly begins by disconnecting its connector and removing two bolts before sliding it to the passenger side while disengaging the rubber pin. The process to detach the windshield wiper motor assembly starts with loosening 2 rods at the crank arm pivot using a screwdriver while you need to remove 2 torx bolts to complete the disassembly. During new windshield wiper motor assembly installation use MP grease on the crank arm pivot then secure it to the wiper link assembly with two torx bolts at 7.5 N.m (76 kgf.cm, 66 in.lbf) while finally meshing the rubber pin before you secure it with 2 bolts at 5.5 N.m (56 kgf.cm, 49 in.lbf) and reconnect the connector. Stop the wiper motor at automatic position before using a round file to scrape hidden serrations on front wiper arm LH. Clean the wiper pivot with a wire brush before securing the arm with 20.5 Newton Meters (arounds 209 kgf.cm or 15 foot-lbf) torque using a nut that requires hinge support. Operating the wiper enables wiper blade inspection for wiping quality and prevention of rear wiper collisions with vehicle body while using washer fluid or water over the window after completing front wiper arm RH scraping and cleaning followed by reinstallation.
