  Q: How do you check and replace the wiper motor circuit on Saturn LS?

  A: To check the wiper motor circuit, probe a grounded 12-volt test light to each terminal at a connector until it lights to verify voltage. If wipers work slowly, ensure the battery is in good condition and has a strong charge; if so, remove the wiper motor and operate the wiper arms by hand, checking for binding linkage and pivots, lubricating or repairing as necessary before reinstalling the motor. If wipers still operate slowly, inspect for loose or corroded connections, particularly the ground connection, and replace the motor if all connections appear fine. If wipers fail to operate, check the fuse; if it's okay, connect a jumper wire between the wiper motor's ground terminal and ground, then retest. If the motor works, repair the ground connection; if not, check for voltage at the motor with the wiper switch in the HI position. If there's voltage at the connector, remove the motor and test it off the vehicle with fused jumper wires from the battery. If it works, check for binding linkage; if not, replace it. If there's no voltage to the motor, check for voltage at the wiper control relays, and if present, have the switch tested. If the switch is fine, the wiper control relay may be faulty. For the interval function, check the continuity of wiring between the switch and wiper control module. If wipers fail to park, check for voltage at the park feed wire of the wiper motor connector when the switch is OFF but ignition is ON, and inspect for an open circuit between the wiper motor and fuse panel. For wiper motor replacement, pry off the windshield wiper trim caps, remove the retaining nuts and washers, and mark the position of each wiper arm before removing them. After removing the hood seal and cowl cover, disconnect the wiper motor electrical connector and remove the mounting bolts to detach the motor and linkage assembly. Pry the link arm loose from the spherical bearing on the motor's actuator arm, remove the motor mounting bolts, and take out the motor. Installation is the reverse of removal, ensuring alignment of the marks made on the wiper arms and shafts. For the rear window wiper motor on station wagon models, remove the protective cover for the nut securing the wiper arm, then remove the nut and washer, marking the relationship of the wiper arm to the motor shaft before pulling it off. Open the liftgate to remove the trim panel, disconnect the electrical connector from the rear wiper motor, and remove the motor mounting bolts. Installation follows the reverse order, ensuring proper alignment of the marks made earlier.
