The rear wiper motor of the 323 can be fitted and removed by disconnection of the negative battery cable, the installation angle of the wiper arm, unscrewing the screw connecting the arm and then removing it. On hatchbacks the motor is usually placed behind a panel in the rear hatch, and on sedan cars the motor is usually placed behind the rear seat, remove the relevant panel, detach the electrical connector and remove the mounting bolts, then carefully slide the shaft right through the rubber seal and do not bend or damage it. To install it, invert the steps of removal and put the rubber seal back in case it broke. On 1979-87 626, do the same, but, after following the first steps, pull the panel out of the back hatch, disconnect the electrical connector and pull out the motor and the mount bracket straight toward you again, being careful that the shaft stays straight through the rubber seal. During installation, move the mounting bracket to the new motor. On 1988-89 626 and MX-6, disconnect the negative battery cable, disconnect the rear wiper arm, and lift the rear hatch to expose the motor assembly by taking off the trim. Carefully take off the rear hatch screen so that it can be used later, take off the motor connector, loosen the bolts and remove the motor. Installation During installation, place the motor and install the bolts, wiring, re-install the hatch screen, and trim, and install the wiper arm and re-connect the battery cable to test the system. On RX-7 models that have a rear glass hatch, unscrew the negative battery connection, unscrew the wiper arm, the bushings, nuts and shaft seal, and unscrew the motor connector and remove the motor off the mounting plate. To install, fit the motor, screws, wiring and close the hatch, and it may be required to replace the shaft seal: reassemble the wiper arm and reconnect the battery cable to test the system.
