• Q: How to service the rear wiper motor on 2007 Toyota Matrix?

  A: Start the rear wiper motor servicing process by first taking away the rear wiper arm cover and then unscrewing the nut and separating the rear wiper arm & blade assembly. The next step requires you to detach the rear wiper link cap followed by using a deep socket wrench (24 mm) to unscrew the washer packing nut at the rear wiper link pivot. Use a taped screwdriver to open the rear wiper motor cover by releasing its 9 claws from the back door glass. There are multiple steps needed to remove the rear wiper motor assembly: first disconnect the 2 rear defogger connectors, remove the two nuts and the rear wiper motor along with its bracket with the shaft cover assembly and finally disconnect the connector, remove the junction switch nut and extract three bolts and three screws to uninstall the entire unit. To install the assembly first position the grommet and thread the three bolts onto the rear wiper motor assembly before tightening them to 5.5 N.m (56 kgf.cm, 49 in.lbf). Then put the 3 screws on the rear wiper motor & bracket and reinsert the connector before securing the junction switch with the nut. One should reinstall the rear defogger connectors and attach the rear wiper motor & bracket assembly to the shaft cover assembly by tightening its two 5.5 N.m (56 kgf.cm, 49 in.lbf) torque nuts. Fasten the washer packing nut at the rear wiper link pivot using a 24 mm deep socket wrench and torque it to 7.0 N.m (71 kgf.cm, 62 in.lbf). The wiper arm and rear wiper pivot serrations require cleaning before you install the rear wiper arm & blade assembly in its designated position while tightening the nut to 5.5 N.m (56 kgf.cm, 49 in.lbf). While installing keep the arm hinge compressed. The wiper functionality should be tested through a fluid or water spray test to verify proper operation while also checking for body interference.
