Steps to Fix One Windshield Wiper Not Working

Steps to take if one windshield wiper stopped working

  1. Cycle the Wiper Arm to the Park Position

    Before shutting the car off, cycle the wiper arm to the park position to make sure the transmission is in the park position

  2. Mark the Position of the Wiper Blades with Tape

    Mark the position of the wiper blades on the windshield with a piece of painter’s tape

  3. Remove the Cover from the Wiper Arm

    With the hood up, remove the cover from the wiper arm with a flat blade screwdriver

  4. Turn the Wiper Arm to See If There Is a Broken Motor or Loose Bolt

    To see whether there is a broken motor or the bolt is loose, turn the wiper arm back and forth. If the nut stays in position, the wiper arm has loosened up. Sometimes you need to remove the wiper arm and clean the threads, and sometimes you can just tighten the bolt.

  5. Check the Condition of the Wiper Arm

    Remove the nut with a socket and ratchet. Disconnect the washer hose. Pull the wiper arm up and off. If the threads are too worn down, you may need to replace the wiper arm.

  6. Clean the Threads

    If the threads have debris, clean them with a 90-degree hook pick

  7. Check the Threads on the Wiper Transmission

    Check the grooves on the wiper transmission. If the threads are too worn down, you may need to replace the wiper transmission.

  8. Clean the Threads

    If the threads have debris, clean them with a 90-degree hook pick

  9. Reinstall the Wiper Arm Once Clean

    When reinstalling, align the wiper blade with the tape on the windshield. Tighten the bolt to the wiper arm and replace the cover.
