The manual contains essential information for installing the windshield wiper motor. Reading through the manual before starting the installation process is necessary to understand how it works.

Not Cleaning the Motor Mounting Area

Dirty windshield areas hinder the motor from working correctly. A dirty motor-mounting area can also cause the wiper motor to malfunction. Therefore, cleaning the mounting area before installing the wiper motor is essential to prevent motor failure.

Failure to Test the Windshield Wiper Motor

It’s necessary to test the motor after installation. This test is essential to check whether the wiper motor works correctly. If the motor doesn’t work, it’s necessary to recheck the installation process.
