Acura 76505-S84-A01 Motor, Front Wiper

You can Select Your Vehicle to check if 76505-S84-A01 fits your vehicle.

To check the wiper motor circuit, begin by examining the wiring diagrams for wire colors. Use a grounded 12-volt test light to probe each terminal at a connector until it lights, confirming voltage at the terminal. If wipers operate slowly, ensure the battery is fully charged and in good condition; if so, 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 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 activate, check the fuse; if intact, connect a jumper wire between the wiper motor's ground terminal and ground, then retest. If the motor operates, repair the ground connection; if not, check for voltage at the motor with the wiper switch in the HI position. If voltage is present, 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 the wiper control relays, and if voltage is present at the relays but not at the motor, test the switch. For inoperative interval functions, check the continuity of wiring between the switch and the wiper control module. If wipers fail to park, check for voltage at the park feed wire of the wiper motor connector with the switch off and ignition on, looking for an open circuit between the wiper motor and the fuse panel. For wiper motor replacement, open the hood and remove the covers from the windshield wiper arm retaining nuts, marking the position of each arm before removal. Disconnect the electrical connector from the motor, detach the harness clip, and remove the mounting bolts to take out the wiper motor and linkage as a single assembly. Carefully separate the linkage from the motor, ensuring the crank arm is aligned with the center mark on the motor bracket before removing the crank arm nut. After detaching the motor from its mounting bracket, grease all spherical bearings on the linkage arms before reinstalling, ensuring to align the marks made during removal. Finally, turn on the wipers to verify correct operation in all modes.
