How to Troubleshoot a Windshield Wiper Motor


Windshield motors come with varied features depending on manufacturer and car model. Some motors have three speeds, others include an integrated interval mode for light and fine misty rain and still others come with reverse to set the wipers under the hoodline. They are all very convenient functions, but a car’s windshield with a broken wiper motor under heavy rain is just as good as a vehicle without brakes. If you have a basic knowledge of electricity or have the patience and like a challenge you can learn the general procedure to troubleshoot a wiper motor.

Step 1

Make sure the battery has a strong charge and is in good condition. Use a voltmeter to get a reading if necessary.
