Windshield Wiper Motor Replacement Service

The windshield wiper motor is a compact electric device that plays a crucial role in ensuring clear visibility while driving. A shaft extending from the motor connects to a linkage/transmission assembly, converting the motor’s rotary movement into the back-and-forth motion of the wiper arms on the windshield. Additionally, certain vehicles like SUVs, vans, hatchbacks, and station wagons have an extra wiper motor mounted in the tailgate to keep the rear window clean.

Signs It is Time to Replace the Windshield Wiper Motor

  1. No Wiper Function:
    If your wipers aren’t functioning at all, it might be due to a windshield wiper motor failure. Before replacing the motor, mechanics typically inspect its power supply.
  2. Improper Parking Position:
    The wiper motor has an internal switch that ensures the wipers park correctly after you turn them off. If this switch malfunctions, the motor needs repair or replacement.
  3. Erratic or Slow Operation:
    Excessive wear in the electric motor or transmission can lead to erratic, intermittent, or slow wiper movements.
  4. Unusual Noises:
    Grinding or clunking noises could indicate wear in the motor transmission or wiper linkages, necessitating a mechanic’s assessment.

The Windshield Wiper Motor Replacement Process

  1. Removal:
    Mechanics start by removing the cowl and any covers over the wiper motor and transmission assembly.
  2. Disconnecting Components:
    They disconnect the plug harness from the motor and detach the wiper transmission arm from the motor.
  3. Unbolting:
    Bolts securing the motor and transmission assembly to the car body are removed.
  4. Installing the New Motor:
    The new motor is installed, ensuring proper polarity and correct alignment. It is bolted securely to the car body.
  5. Testing:
    Mechanics cycle the motor multiple times to establish the park position. The linkage transmission assembly is reattached to the wiper motor.
  6. Final Steps:
    All covers and cowling are reinstalled, and the motor’s operation is tested on wet glass.

Safety Considerations and Maintenance Tips

  • Safe Driving:
    It is safe to drive with a faulty wiper motor in clear weather conditions. However, during adverse weather like heavy rain, proper wiper function is essential for visibility and safety.
  • Maintenance Tips:
    Regularly replacing the rubber inserts in the wiper arms (every 1 to 2 years) enhances safety during adverse weather. Additionally, when replacing the wiper motor, lubricating all the linkages in the wiper system is crucial.

 

Remember, a well-maintained car involves more than just addressing windshield wiper motor issues. Regular checkups, including tasks such as car oil change, checking car spare parts, inspecting the car bumper, and monitoring car coolant and the car’s AC system, contribute to overall vehicle health and fuel efficiency. Routine tasks like oil filter changes and checking the air filter in the car, along with addressing issues like car jumps, repairs to car shocks, and investing in car detailing services, are essential aspects of car repair and maintenance.¬†
