How to Repair Subaru Windshield Wiper Motor Failures

Step 4: Test the Motor

Reconnect the battery temporarily and use a multimeter to test voltage at the motor connector. If voltage is present but the motor does not run, the motor may be faulty.

Step 5: Replace or Repair the Motor

If the motor is defective, remove it by disconnecting mounting bolts and electrical connectors. Install the new or repaired motor in reverse order.

Final Checks and Testing

Reconnect the battery and turn on the wipers to ensure proper operation. Verify that the wipers move smoothly and stop at the correct positions. Reinstall all panels and covers.

Tips for Prevention

  • Regularly clean electrical contacts with contact cleaner.
  • Inspect wiring for signs of wear or corrosion.
  • Address any wiper issues promptly to prevent motor damage.

Proper maintenance and timely repairs can extend the life of your Subaru’s windshield wiper motor and ensure clear visibility during adverse weather conditions.

If your Subaru’s windshield wipers are not functioning properly, the issue might be related to the wiper motor. Repairing a faulty wiper motor can restore clear visibility and ensure safety during bad weather. This guide provides steps to diagnose and repair Subaru windshield wiper motor failures.

Identifying Wiper Motor Problems

Before attempting repairs, determine if the wiper motor is the source of the problem. Common signs include:

  • Wipers do not move at all
  • Wipers move erratically or stop mid-sweep
  • Unusual noises when operating the wipers
  • Wipers move slowly or intermittently

Tools and Materials Needed

  • Screwdrivers (Phillips and flat-head)
  • Socket wrench set
  • Replacement wiper motor (if necessary)
  • Electrical contact cleaner
  • Multimeter
  • Gloves and safety glasses

Steps to Repair the Wiper Motor

Step 1: Disconnect the Battery

Ensure safety by disconnecting the negative terminal of the battery to prevent electrical shorts.

Step 2: Access the Wiper Motor

Remove the wiper arm covers and the cowl panel under the windshield. This exposes the wiper motor assembly.

Step 3: Inspect the Motor and Wiring

Check for visible damage, corrosion, or loose connections. Use electrical contact cleaner to clean contacts if needed.

Step 4: Test the Motor

Reconnect the battery temporarily and use a multimeter to test voltage at the motor connector. If voltage is present but the motor does not run, the motor may be faulty.
