The windshield wiper motor on a 1998 Honda Civic sits underneath the hood of the car and is mounted to the firewall. The motor controls the function and movement of the windshield wipers. While there is no service life for the Civic's wiper motor, it will need to be replaced when the motor starts to hesitate. The motor looks like a small canister. Replacement motors can be purchased from most auto parts stores or directly from a Honda dealership. Difficulty:Moderately EasyInstructions
How can I tell if the switch is a problem or if the motor is the problem?
My wipers respond in all positions except the off position. I drove around for a while (with the wipers stuck in the on position of course, the first speed) and after some time the wiper gets stuck near the bottom position now and then. If I change to the next speed it will become unstuck. I just priced the switch and it was about $120 at Bridge auto parts. In any case I will look online to save $$.
There's only 3 things it could be- the switch, the motor, or a bad wire/connection. Do you have a multi-meter and know how to use it? If so, find MelJ and download the service manual from his sig and diagnose for a faulty wiper switch.
