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 at the terminal. If the wipers operate 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 the wipers still operate slowly, inspect for loose or corroded connections, particularly the ground connection, and replace the motor if all connections appear fine. If the wipers do not operate when activated, check the fuse in the driver's side interior fuse panel; if the fuse is intact, 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, noting that the cowl cover must be removed to access the wiper motor electrical connector. If voltage is present 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, and if it doesn't, replace it. If there is no voltage to the motor, check for voltage at the wiper control relays, and if voltage is present at the relays but not at the motor, test the switch; if the switch is functional, the wiper control relay may be faulty. For an inoperative interval function, check the continuity of all wiring between the switch and wiper control module. If the wipers fail to park when the switch is turned off, check for voltage at the park feed wire of the wiper motor connector with the switch OFF and ignition ON; if no voltage is present, look for an open circuit between the wiper motor and the fuse panel. For replacement, remove the wiper arm mounting nuts, mark the position of each wiper arm to its shaft, and remove the arms, using a battery terminal remover if necessary. Then, remove the plastic cowl cover, disconnect the electrical connector from the wiper motor, and take out the wiper motor and link assembly mounting bolts to remove the assembly from the cowl area. Use a screwdriver to pry the linkage rod from the crank arm pivot of the wiper motor, remove the crank arm nut while marking the relationship of the crank arm to the motor shaft, and detach the crank arm from the shaft. Finally, remove the wiper motor mounting bolts and detach the motor, with installation being the reverse of removal.
