To check the wiper motor circuit, ensure the battery is fully charged and in good condition; if the wipers operate slowly, remove the wiper motor and manually operate the wiper arms to check for binding in the linkage and pivots, lubricating or repairing as necessary before reinstalling the motor. If the wipers fail to operate, check the fuse and, if it's intact, connect a jumper wire to the motor's ground terminal to retest; if the motor works, repair the ground connection, otherwise check for voltage at the motor when the switch is in the HI position. If voltage is present at the connector, remove the motor and test it with jumper wires from the battery; if it works, check for binding linkage, and if it doesn't, replace the motor. If there's no voltage to the motor, check the wiper control relays, and if they have voltage but the motor does not, the switch may need testing. For the interval function, check the wiring continuity between the switch and the wiper control module. If the wipers fail to park, check for voltage at the park feed wire of the wiper motor connector. For wiper motor replacement on Sephia and Spectra models, remove the retaining nut trim covers and nuts from the wiper arms, marking their positions before removal, then disconnect the electrical connector and carefully pry the linkage loose from the motor arm. Remove the mounting bolts and the wiper motor, detach the linkage from the cowl, and grease the pivot points before reinstalling, ensuring alignment with the marks made. For the rear window wiper motor on 2001 and later Spectra models, remove the rear wiper arm and trim panel, then take out the mounting bolts and motor, disconnecting the electrical connector before reinstalling in reverse order. For Sportage models, remove the wiper arm mounting nut trim caps and nuts, mark the positions, and remove the arms, then take off the cowl cover and disconnect the electrical connectors before removing the motor/linkage assembly. Separate the linkage arm from the motor, remove the crank arm, and then the motor, reinstalling in reverse order while ensuring proper alignment. For the rear wiper motor, mark the position on the glass, remove the arm and handle, disconnect the electrical connector, and take out the mounting nuts before reinstalling in reverse order, ensuring correct orientation of the wiper arms.
